hah yeah i figured i'd make flies as annoying as they are in life :P
you are 100% right with arenas, they lack clarity on how many enemies are left to defeat
regarding stutters: sadly it's a godot glsl thing, where the shaders are compiled on a runtime, the simplest fix would be spawning the objects that are causing the stuttering at the beggining of a game to let the materials compile.
I just run out of time to do so 👉👈
thank you for your comment!
