each key opens a specific door. if it doesn’t open one, look for another. i think we could have made this clearer, but unfortunately we didn’t come up with a good method for that in the time we had. sorry for the confusion!
i’ve experienced some choppiness with the framerate too, so you’re not alone. for me, it’s usually just on the main menu and it goes away after a few seconds of playing. it might depend on your computer specs?
thanks for the feedback and for playing!
