I'm very sorry for the incident and I wonder how it's possible, the only reasons could be, for example, did you accidentally extract some files outside the folder? Or deleted some files? Since extracting or deleting 1 file could damage and the game won't work anymore. Have you tried deleting the game and redownloading it? And have you checked to see if you were pressing CTRL and not another key? Or maybe your keyboard key isn't working properly. Let me know!
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
