In my humble opinion, this is a top tier puzzle game. The premise is reminiscent of 3d Logic, only 2d and with a different design, and to be honest, I prefer this one. Not only is the new pixel exterior amazing, the controls are easy, and the game itself is simple to understand, while still providing a challenge. This alone would makes the game great, but the music brings it to a whole new level. The music by itself is enough to make me want to delve further into this.
The Developer listens, it's color blind accessible, the music is great, the controls are easy to learn, the graphics are great. I am normally very critical with my ratings, and I believe this game has well earned a five out of five.
