theme: not bad, evil cube is a solid idea.
Polish: The game is decently polished, the background music was a little annoying, but the sound effects were good.
Art: The neon look is really good; the flying objects were a bit distracting, but the game looked good.
Concept: it took me a while to understand, but the idea is good. It needs some adjustments, but it's not bad.
enjoyment: once you understand how the game works its actually kinda fun, it's hard to see a little, but the gameover all it good.
