heres the ideas i 'used' to put into my DMs (i put 'used' because i cant access my addons now):
- say its a volcano-island themed world, put a super powerful level in the bottom of the volcano and you must navigate up the side and then down into the volcano to this platform, and lava would occasionally rise up to the top and blast out, use cannon balls to make the rocks flying out, its a bit 'Donkey Kong' themed but still cool
- and everyone spawns on the shoreline around this volcano island
