The game is overall pretty good, but it has two flaws in my opinion: It dosnt really use the theme that much, its simply that the ennemies are made out of colored rectangles, and it gets somewhat repetitive. However the game is graphically good, it has a really great feel to it and so on. Although i think the game is good, i think you will get a lot of not that great reviews because your game doesnt have one really great thing, wheras a lot of them have either a great concept, a great art style, great gameplay... wheras yours is good in every domain, but it doesnt have that one defining quality. A good game nontheless
Also, I'd love it if you would consider playing my game and giving me feedback.
