Great little action platformer. I could see this Turing into a metroidvania, that I would play. I have two suggestions, if you run past the bats they should loose aggro at some point. Second the purple balls the plants shoot, it would be cool if I could hit them and know them into enemies. Also, I think the attack animation is too stiff.
With my minor gripes in mind, this is better than anything I can do on Godot currently.! Great graphics, great tutorial, overall awesome job well done!
