Hi! This game is my introduction in shader world. The rules are simple: paint whole screen with a certain color => win. BUT... The image is morphing! BUT... You can go back or forward in time.

Controls: 

LMB - Pause and Submit, RMB - Show hint, Mouse Wheel - Go back or forward in time 

F - Fullscreen on/off, R - Restart, ESC - Quit

Hope you like it!
