the game is very well thought-through. i had a lot of fun with remembering what i even NEEDED the keys for, beause hitting your head to crouch is just such a FUNNY idea and i forgot that i could do it all the time. i played multiple games that used some sort of "you get different controls every now and then" mechanic but yours kind of felt a lot of smarter, than some of the others ive seen. Especially since in your game i actually needed to go left sometimes,(which confused me so much). I absolutely love it! (it however felt kinda weird that everything took place in the lower 1/3rd of the screen, so you maybe could have made it more of a side-scroller, but bigger. anyways - great game!!)
