It is basically the same as Viscera Cleanup Detail, but in a fantasy dungeon, with hazards. And you're a goblin maid, which is a strict upgrade imo.
I would say the cleaning itself is a bit more simplified, though it's possible they'll expand that for the full release. But you have the added mechanics of needing to avoid traps, restore furniture and fixtures to their original positions, and deal with monsters.
Also your mop is a slime impaled on a trident, and once it's full and dies, you need to feed it to a mimic. You can also impale other things on the trident. And feed those to the mimic. You can even name the mimics! Though if you're not careful, they will also eat you should you get too close.
Honestly it's a very charming take on the idea. Less complexity, but more variety. And you can die, so remember to activate the respawn points.
I'm looking forward to seeing how it ends up.
Though I still consider it in the "podcast game" category.
