Is there REALLY one button?

Don't you love a game that over uses the same mechanic at the point where it becomes boring? Me neither! So here's one!  Why do characters talk like that? Why is everything black and white? Why does the game do that when it never told me it could? WHY DO DOORS KILL ME? 

I DONT KNOW! but its in the game! and its weird. and. yeah thats all thats my description

having problems with some levels? here is me playing the game if you have any problems :  https://www.youtube.com/watch?v=cULIuXlXKB0

KNOWN  BUGS : 

Sometimes blocks are missing. doesnt affect plateforming so its basically just visual

level 11 just does not work. its there. but its empty-ish. you can go trough it (and you have to)  but its bugged so sorry about that
