I can't seem to make progress on Level 3. I have the item you need and try to use it on the fragile door...but nothing happens :(
Same here. Something is not working with certain machines.
Hmm, that is strange, and I'm sorry this is happening. I've heard of this issue happening with others but haven't been able to replicate it myself.
May I ask, are you running the game on a 120 or 144Hz monitor?
