I don't think it's bad but it was unclear what the controls were or what my objective was at first. The art was decent, but the music was very repetitive. Would defiantly recommend adding more layers, or making it longer before looping.
I see that now but I played the game by download so I didn't see the description right away. I would just recommend for next time to have the controls shown somehow in-game. It can be a button that makes the controls show up, or just have them floating on screen, or shown when the game launches.
