Good concepts are what I strive for, so I'm glad I hit the mark.
I should've made a lot of the wall jumping and overall platforming a little less demanding, since for me it's not too hard since I made the game. Need to build levels with someone with no experience in mind, which is a design factor I need to get better at.
I find the best way to get vertical height quickly is through sliding up walls (Which isn't really explained :/) So instead of Rapidly jumping between the two walls, instead jump and slide up the wall. You gain a lot more height by doing so, can easily test it by jumping by a wall, and then jumping while pushing into the wall.
Dang, I thought I didn't have any game breaking bugs in this one! I guess I need to make a R key reset the doors collision trigger.. I guess Godot doesn't count teleports as leaving a body.
Thanks for the extensive review!
