Looks okay. Animation is smooth. Not much going on here, though. Also, the language is wrong.

Fun! Keep working on it

Game only had blank screen when I clicked play.

Edit: Started working and it's pretty good, too many enemies to quickly but that's fine if you were trying to make a bullet hell game.

I think the introduction of other enemies plus a bit of art could make this a much better game than it already is, the idea is good and the controls it has are very good!
