Thanks a lot! Yes, i´ve already heard of the problems you mentioned, i´ll add checkpoints next time i make a game like this, and i´ll definelty fix the controls and the collisions. About the color: I realised it´s hard to see, but i didn´t want to have it too bright, because i wanted the doors to stand out. But i think especially on some screens it´s really dark and i´ll think more about it next time!
