I must say i really liked some of your ideas. Like apple throwing horo, Gurren Lagann styled boss (you can't forget those glasses after you see them), and obviously the whole 8-bit world. The biggest problem of the game is that the difficulty level is damn too low. It cant be even compared to the crazy level of the touhou series, and I think it's mainly because of the shield power up. It stays up for too long and shows up way too often, imho the game would be much better without it.
