So first, I thought how easy this game is, but then came the.... spinning things? Why are they not spikes. jk. So overall, I think the difficulty curve was very good.
The presentation is excellent, (especially for you, if I can say that.) All fits the style. Though the particles, and especially the way they move is a bit... contruct-y? Idk, but I see bad looking particles from C3 pretty often. The sprite for it is good, but next time if possible maybe tweak the movement idk.
The concept is good. It's simple, well explained.
Good game. Good developer.
