I liked the autoaim and that you included at least two different mobs and two bosses.
I managed to save the universe with less than 8 seconds to spare! Talk about clutch!
Some improvement suggestions:
- What is the green item that drops from enemies? Is it a heal? It's not clear from the "default godot icon" they have. XD
- The hitbox on moving platforms (boss 2) is was not very clear. I thought they wouldn't hurt as long as I wasn't below them or between two of them (avoid getting crushed), not that they hurt if I stood on top. XD
Good job!
