The game looks really nice. It seems like you've certainly put a lot of effort into making the game look as good as possible. That includes the ever-generating corridor and the cute skull that is chasing you down. I would also praise the 50/50 option block looks extremely intuitive, allowing the player to know immediately what is the pros and cons of each block.
For the gameplay, I think the game is too luck-dependent, where I think the best course of action is just randomly pressing buttons and seeing how far it goes. It would be good if there were some way to make the choices more impactful and/or controllable i.e. weighted chances etc.
Anyway, I think the game is still very well made. Keep up the good work!
