Extremely good submission! Fun to play, simple, very polished. Sound design and music was great. Love the characters. It has good progression in difficulty, and it rewards skilled gameplay. The only minor suggestion I would make would be to have some kind of indicator of progress other than the increasing numbers of more difficult enemies. I wasn't able to last long enough past the third enemy type to know if there's an ending, but maybe a timer like in vampire survivors or a point system or something more subtle maybe, giving you a heads up the next enemy upgrade is coming. Otherwise, really enjoyed this game. Good work!
