Its pretty easy really, I got the model and animations from mixamo, take that into Godot and place it into a viewport, then set a sprite to show the viewport. The spawning bugs should stop after you kill 10, perhaps something went wrong :/
It is really that easy?! Thank you for the explanation!
It's more likely that I was too impatient and didn't even kill 10 bugs. Will definitely give it another try :)
