Your game is pretty interesting. There is a lot of potienal in this machanism. The graphics and audio need improvement but I totally understand why it is this way.  There is few things that could be better though. First the color scale, I wish the scale could be large so not located in the middle of the screen. I also would be better if I can control the color with the keyboard. Also, somethings two objects seems to be the same color but I can't pass through them. Overall, it is a pretty good game.

If you have time, please try out my game, thank you
