Im curious why did you pick 3.6 over 4.4 or 4.x?

You can only get the window size after the window is ready, if you were on godot 4 that’d be with an @onready var but I don’t remember how to do that in 3

You can simplify your rng by using global randomize(). Then you won't have to remember to create a new random generator, and you can generate random stuff with randi_range() instead of rng.randi_range(). That is, if you don't need several differently-seeded random generators.

Couldn't read through the whole code because of messed up formatting.
