Wow that’s weird. That last door is loading from one map to another map which houses the final room. The first map has all the rooms and you just teleport from one to the other when you go through those doors. I set it up this way so the final room fully resets if you miss the cheese at the end. So you are loading more for the part you were able to play and a lot less for the part the computer crapped out on. I know it takes a toll to jump between maps but to say you don’t have the memory for it just doesn’t make sense when you have the memory for the larger part of the game. But I’m not that kind of computer person so I’m sure my IT friends would laugh and tell me exactly what’s going on. Lol
Regardless glad you enjoyed the levels you could play. The final room is a piece of cheese being tossed in the air over a hole and you gotta dash to catch it so you didn’t miss much.
