I really enjoyed this one! The sound design was good, I love the sprites, and the lightning striking the flies that remain at level-end is the funniest thing I think I've ever seen lol.
For anyone playing during the jam, look at the Pursuing Pixels frog with the beatbox dance perfectly to the tune of the in-game track hahaha.
My only real criticism is that there should be some indicator for how many shields a fly has. Some shields seem to take more hits than others, so it would be nice to see what you need. I know the king takes 2 hits every time, but some of the normal ones seemed to need two hits as well, though perhaps it was user error and I wasn't quite hitting them.
