I've wondered the same thing. I haven't even seen any play on mine (which is discouraging to say the least). Unfortunately for my server, most players only play "grind" dungeons, which I find kinda sad and boring.
I had someone try my contest entry, and they sent me a nasty letter saying I didn't put an exit. However, I do have an exit. In the final room, I altered the tilt of some misty tiles to create at walkway going up into a cavern system, which is where the final encounter occurs and the exit. I hope the Dev's didn't try mine and fail to see the walkway as well lol.
If anyone is on Oasis and wants to give it a try, it's "The Lovely Bones". Moderate solo difficulty, takes roughly 15 minutes to complete (give or take 5 minutes depending on how efficient you are with your mana and play style/avatar chosen).
