I was a bit worried about the sensitivity range, but it's good that the dial worked because I hoped people would use it to fix the problem. I though I gave it fullscreen but I guess it didn't work. I was actually really worried about the music because I had no idea what to make, because I've never written music before, so I just recorded me doodling on my piano and guitar. About the pointer lock, I tried to just make the pointer invisible, but I didn't have a texture for that at the moment. Thank you for the advice, I'll try to fix those after the jam!
