Awesome!! Such a nice intro as well!
Testing feedback: it doesn't seem to detect my PS4 controller sometimes (not the connection, tested it simultaneously with Godot game picking it up); perhaps especially when having used keyboard input and then trying to switch to controller?
I would let people skip the cutscene at the beginning when playing for the second time (for instance when you only read the controller inputs and then couldn't find the attack key before you were on your last life).
