Yeah Godot the future haha! Yes without Jolt, the physics was so trash.
No worry about the small buzzing, it's the noise caused by spotlights x)
You know, when you're in test during class. There is no sound, except the lights which are buzzing. It's a very disturbing noise, and I wanted the same thing for my game (to get an disturbing atmosphere)
Thank you for the feedback anyway :) And I'm glad you liked it :D
