no files were deleted. i didn't delete and reinstall because honestly i wasn't sure that that would fix anything. I tried literally any key that i thought would work or should work. my first guess was the "C" key for crouch like any other game, when that did not work I tried clicking or just walking straight into the tunnel but that did not work either. and then that's when i tried literally every key on my keyboard to try to crouch. i didn't do anything to the files, just installed and started playing. seems like i might be the only one with this issue since everyone else loved it. i could try deleting and reinstalling if you think that could work. thank you for responding, im not a dev so i have no idea what would fix the issue lol
