Thanks! The door is indeed just randomly placed, scaled and colored on a random painting (which can reappear). Integrating the doors to fit the paintings would be very could, I just did not have enough time.

Thats a great idea! I just made the modification, now you find a number of room and try to get the best time. Obviously that goes even beyond the 3 hour mark but im here to chill.

Edit: the rooms are indeed easy except a few (its can be strategic to just skip those), the goal is to find them as fast as possible.
