This was a cool game and the main complaint I had was the lack of content! I wanted more to experience. The puzzles were a little simplistic which makes sense, being that it was only a single short level. I think some more utilization of sound FX and music could help as well. Maybe some particle effects when a ball tries to enter the wrong color, or maybe some type of effect/sound when the ball goes into the correct color. Just some more game feel to make it stand out a little more. You did have some nice polish overall. The inclusion of the gamepad was nice!
