Mutant Alley: Dinohazard is a 2D and VR first person fantasy sex simulation and a complete remake of the original Mutant Alley: Do The Dinosaur.



The new interaction system will deliver an awesome experience on a 2D screen but is even more immersive when used with a VR* headset.


Instead of cycling through animation loops you can touch, lick, grab and penetrate the characters in any way you want by either using your mouse (2D) or your hands (VR*).


The characters will physically and verbally (voice acted) respond to your actions and will remember your previous performances. Sliding or penetrating certain body regions will even emulate friction and resistance. Further features are dynamic breathing, genitalia and accessoire physics, bulge grow during foreplay and lots more.


Do you like to foreplay? How about some sexy accessoires for your partner? Mutant Alley comes with a rich set of options to customize your experience.


Mutant Alley: Dinohazard uses Unitys HD Render Pipeline to bring you high quality graphics and effects which delivers a more realistic and atmospheric game experience.


Explore the environment and find new ways to shape your experience, how about calling the Mutant Control Unit to have your partner tied up for you?

i love this game but i have a problem, the setting screen is really small, i can see what's written. Is it my screen or is it a bug of the game ? thanks in advance

the coming updates definitely will have a larger menu:)

Thank you for the answer :)

(1 edit)

I'm trying to find a good laptop ,for I can use the vr. I don't know if this laptop would be combatible the laptop is named 

MSI - Delta 15.6" FHD 240hz Gaming Laptop - Ryzen R7-5800 - Radeon RX6700M - 1TB SSD - 16GB Memory - Black 

so can someone help me find out if this one is good or not. thank you

P.s the Vr headset will be quest 2


Love the game! Having a lot of fun with it ;) Though, how do I switch to the penis? Pressing/holding down T is only bringing out the tongue for me.


The player penis will be available in the July update

Awesome! Thanks!

Love the new update! Can’t wait for the next one

already in the making:)

I love that itch literally did not inform me about this until TODAY. -_- still though it's awesome! A couple minor problems I have been having: I can knock on the door but I otherwise haven't found any other of the environmental interactions you mention. Also a couple things are a bit spastic when he's on the ground, like I've noticed if you fiddle with it you can get him to raise his right arm as if you're going to rub his bicep or lick his pit but it keeps jumping around and I can't get him to hold it up for more than a couple seconds to interact with it and when you move around while he's in that position it's like you're on a trampoline.
I need to test this further but the controllers have area ISSUES when pointing. They seem to work fine with positioning but pointing at the menu I have to have my controller down at my side and fiddle with it just right to get it to aim at anything or the pointer seems locked on one of the corners even when I move it around.
Does this version have any mawplay? I saw some good detail when I phased my face into his but I wasn't able to initiate anything. 
A couple of suggestions/comments:
It would be good if there was a way to get him to bend down a bit. Far be it for me to complain about being tall (I REALLY love how in this version you can tell how HUGE he is compared to you) but I can't really reach his arms or face when he's standing up,especially if I'm aiming to lick his biceps or pits. I need a stepladder to reach that boy!! <3 I love the size though definitely do not make him smaller!!
I am SO glad you kept the voice for him, I really love it and his lines are GREAT.
This is 100% a me thing but I love the vore reference to him not eating you, I would love more references to that or at least more vaguely threatening references like that. The danger adds to the excitement.
The new model is WORLDS better.
I really hope he gets a bit more dominant about the foot-related stuff, he's very passive in that regard and even is like "No don't do that" rather than being in control.
I hope there are more options for him to be more the dominant one in control of the situation, maybe telling you what to do and you get good reactions for following his commands etc.
The tongue is a tiiiiny bit too long and it makes it kinda silly.

If I think of more I'll let you know! I really hope this one gets some more updates because it feels like a VERY impressive start and it definitely makes me want to check out your main game now that I've played these two.


thank you so much for this large feedback, this helps me a lot! As for the stage interactions: you can pass the chainlink fence doors in the front and back of the level, there you will find a pay phone and a soda machine:) 


also: I really don’t often get as detailed feedback like this, would you be interested in joining the MA beta program? If so please contact me:)

Ahhh okay I didn't realize I could pass those! I'll check that out tonight, thank you!

Absolutely! That would be absolutely awesome, and I love giving detailed feedback so I would love to! I can send you a PM on Twitter or FA if you would prefer one or the other? 

Wherever you like!

This game‘s amazing! can this game be updated by this website? or only could be updated on steam? so nice I can,t control myself to share it on our country's video website! !! 

hey there, you will receive free lifetime updates on every platform:)

That’s awesome!!!!!

thank you!

It's not letting me grab it? I enter touch mode and the green thing appears in the middle, I press left mouse button and nothing happens? Also is there a way to suck him or ride him like there was in the first game? Thanks 

I've tried restarting, didn't work. I've lowered the quality settings, also didn't fix it. My mouse isn't broken because it works on other things. Am I missing something? Thanks 

that sounds strange, have you tried lowering the game resolution?

Yeah. No joy :/

I can use the hands at the start, but if I switch to the tongue, the hands disappear and I can't get them back even after putting the tongue away

Maybe I will try deleting and reinstalling 


definitely reduce the game resolution 

I got a problem with the patreon version. So a while back I download it from patreon and it make me accept the authentification. But at the end of the month I decide it so get out of patreon for economic problems. I still could acces the game but now it start it to ask again for authentification and now I can acces it. Might better wait for the next update to buy it.


yes, the patreon version will require to be reauthenticated every month.

Ok, when will be the next update?

Hopefully at the end of next week. I’m done implementing everything but I have to wait for the author and then have the new voice lines recorded.

Any chance we will see the watersports related content in this version, like we had with the last version?

actually that will be in the first update, which will be rolled out in May

So I tried this with my Valve Index but it doesn't work, turns out I had Oculus OpenXR on.

Anyone with an Index opening this game and wondering why it's not switching to VR automatically, I switched to the SteamVR OpenXR. If you're using OVR toolkit and are/have used it in games played through the Oculus store, you will need this fix. 

Go through Open SteamVR > Settings > Enable Advanced > Developer > Switch OpenXR runtime to SteamVR. Boot up the game again with SteamVR open and now it should work.

thank you!

Holy hell, that ram requirement...Is that for the VR stuff solely, or does it require that much RAM for 2D stuff, too?


16GB isn’t that much ram for an HDRP based game.


Kinda is when you're limited to a 6 GB RAM computer, heh. Ah, well, wishful thinking.

I got it on steam and it works fine when I play it with out my Oculus Quest 2, but when I play it with the Oculus Quest 2 the game brakes, my hands go flying around everywhere and when I try to open the menu I can't us it because my hand are flying around, I tryed to run it in steam vr but it crashed, I still like the game but I hope these these problems get fixed really soon.

hey there,

you are running the game on a too high resolution. This caused a massive lag and so the physic updates fail. Please reduce the resolution in the graphics menu.

How can i stroke him faster? Going foward with the mouse is pretty fast, but going backwards is preeeeeeeetty slow, i tried to change the settings, but didn't change the speed at all

yes, that’s the friction emulation. I will add an option to make deactivate it in the future 

So if i buy the game on itch.io and it gets some updates in the future. Am i able to update it or do i need to purchase the new version of the game??

All future updates are included 

HI. i have a question about how to install the game on the quest 2

hey, the game does not support it. Unity’s HD-Renderpipleine wasn’t made for it:/ But you could use AirLink

Hi, great game! Just wondering though, it says that you can touch his feet to change the position but it doesn't seem to do anything for me. Is this a bug/unfinished feature or could I be doing something wrong? Thanks!



I forgot to remove the feet hint for the first release. The  May update will feature the Layed down / feet Loft pose which will be triggered by touching his feet.


Hello! I really enjoy this game a lot! Are you planning to re-implement the riding and penetration mechanics from the previous game? I would absolutely love to be able to ride him hehe


yes! I absolutely want to have FPS f**** mechanics in the game. Im currently working on a good concept 


can’t wait! :D


Loving the game , I have a question though will there be any future updates? just like "mutant alley do the dinosaur" ??

in fact, I’m already working on the first update which will be released in may:) so yes, I have big plans!

I don't know if this is a bug or not; but every time I get to the edging phase, and I stop for even a little before the edging bar fills up, The climax bar completely resets itself.

hey there, no that’s on intent. Because you’re ruining the climax when stopping during the edging:)

Hello, this game will be released on Steam?


hello, it already is:)

Thank you so much! Already on my wishlist! :3


Congrats on the release, Tyranno!

For anyone wanting to know more about this game, Chapomon made a very thorough video review of the previous game (this one is essentially a remake of the original Mutant Alley). The two games are different, but the review encapsulates why I was excited to see the new Mutant Alley coming out.


Thank you!
