I enjoyed the glowy levels, not the biggest fan of "I'm literally just a rectangle" as a protagonist, but considering the shape-shifting mechanic and the rest of the game's style I think it works well here, just wish you at least threw some black rectangles for eyes on him. The game gets a bit challenging and the levels are pretty neat with how they use the whole shape-shifting thing. I loved the transitions and ambiance, the game feels really polished. Good job on the game!
