Firstly, I was fooled by the graphics, I thought it would be an easy game. It is rather challenging. That's what I like about the game. You might think you would rushed the game, yet at some point you need to take a moment to figure the flow before reaching your objective. The graphic is actually fine, although I think it would be better if it has a theme of it's own rather than boxes and triangles. Alien dungeon maybe, the alien shoots projectile? I don't know, perhaps you could make every level having different theme if you want. It will look more appealing. Adding variety of obstacles and objective would make the game much better too.
