I liked the puzzles in this game! There was a point in the 2nd level where I started to get nervous because the level kept going on and on. Very cool concept! I would've liked to hear some music and maybe some sound effects for the buttons or walking. Also would be cool to see more of the palette, but having just black and white, and red for the buttons fits the art style pretty well so I wouldn't change much. Again, very cool game, enjoyed it alot!
