im kinda stuck lol, are you supposed to be able to open this door with the security key or something? idk what else im meant to be doing right now
if you just want to finish the game, use the next door to that and look for a mirror. i think you can go by yourself after that. the security key is supossed to get in a room full of iron bars with auto jump. my apologies if it is not able thanks to the bugs, an update is coming soon to fix all of that.
