It is pretty fun, but way too hard. I think Wave 4 (which I can't seem to pass lol) is much worse than the rest because it overwhelms you very fast if you fumble around your shapes like I do. I think there needs to be some way to give the player more time to think, because often times attacks don't go the way you expect it to because of the bullet count making you try to think quick.
It is very creative though. And also love for fairies of light <3
