I'm quite surprised with the response so far, because this hold was intended as a sort of joke. Maybe you are just being polite.
I had an idea and then quickly added some rooms around it. Most of the rooms have been made without much thought and with very little testing. Judging by the feedback, perhaps it could be turned into a proper hold with some tweaking.
The absense of checkpoints was intentional, but I'm not sure if it was the correct decision.

×This is perhaps the biggest clue to solving the entire hold. I must warn you that it is something of an anti-climax if you have already solved seven of the rooms.
