Super fun game! Really enjoyed the fluid platforming! The art looks really good, too! I wonder how many waves are in this game since I was only able to get to wave 4. A few notes that I hope come across as helpful:
1) The hitboxes of the enemies are really big!
2) It would be nice if there was a way to recover life! (Completing a wave fully restores or recovers 1 life?)
3) I got a hit (only one time, but still) by an enemy that just spawned
4) more juice when you defeat an enemy / hit an enemy (hitstop, screenshake, enemy noises, etc)
5) The background and some of the sprites of the platforms are not connected and you can see a line going through them. If I remember correctly, there is a pixel perfect camera component you can add to the camera to help with that
Otherwise, great job! Super fun game!
