I'm imagining a deep dungeon with graphics similar to Smileton but we will be turning its room-flipping background gimmick into an actual mechanic.

There will be an interactive lever or item which flips around rooms on the current floor and reconfigures the layout into a new route.

This can be used strategically with some limitations to bypass dangers, or perhaps to gain access to rooms which were previously inaccessible (in a Zelda-esque puzzler way.)

Due to floors with this mechanic perhaps taking longer and to avoid tedium I think it would be an improvement to have bosses every 5th floor, to a maximum depth of 50 floors only.

Carrots should be useful in some way. Also the devs shouldn't be afraid to combine ideas from different kinds of side content like the lost actions from bozja; we can slot actions not usually suited to our current role.
