Thanks so much! I just fixed the movement using move_and_slide instead of move_and_collide so that it adjusts the angle automatically when you touch walls. (Of course I can't submit it) But you're right, the movement was/is super sticky in comparison. Now I'm breezing through the game.
I'll turn the footsteps down to a lower volume. :)
Working on making the energy rechargers tell all of the nodes to save their state, so it works as a respawn point. The difficulty can be pretty brutal to run it all in one shot.
Thanks for playing!
