Thanks for the feedback; I've got an idea in mind for a volume slider which will start... probably at the halfway point or lower so you don't get BLASTED.
Keybinds will be tricky. Will mess around with more comfortable setups!
I didn't want it to be T O O unforgiving... maybe a difficulty slider in that case >W>
A 'Free-play'/Gallery mode is absolutely something I've had bouncing around in my head. This is my first coding project so implementing all this stuff is a new learning experience every time.
