Grumpy Dungeon

You are the janitor of a very old, very proud, very talkative dungeon. Something has gone wrong in its depths, and the little glowing wisps that live down there need rescuing.
Fight through its halls. Save its spirits. Regrow its garden. Collect all the wisps.
COLLECT ALL THE WISPS
The dungeon is full of little spirits worth saving. Each biome has its own species, wisp rooms turn up in different places every run, and the deeper you go the nastier the twists get. Filling out the collection is the whole point of the game, and it is also how you get stronger.
YOUR ITEMS ARE ALIVE
Any wisp you rescue can live in your kit. Put one in your sword, your dash, your hammer or your spit and that move takes on the wisp's element. Land a big enough hit and the wisp itself bursts out as the attack. Your favourite doesn't have to stay in your pocket either. It flies along beside you, fights at your side and delivers your ultimate when you need it.
GROW THEM. EVOLVE THEM.
Rescued wisps come home to the garden. Plant them and look after them and they grow into stronger versions of themselves, and with enough care they evolve into something new. If a wisp falls in battle it turns to essence. Plant that too and the garden will grow it back.
THE DUNGEON NEVER SHUTS UP
The building itself is your constant companion. There are giant eyes in the walls and a running commentary on your route, your build and exactly how many times it has had to save you. When you go down it pulls you out, puts you back at the door and makes a note of it.
BIG GIANT BOSSES
At the bottom of every biome something enormous is waiting. You take it on with the wisps you have raised, and that is where you find out whether your build is any good.
GET YOUR GEAR BACK
If you fall in the deep, the gear you were carrying doesn't vanish. Something down there picks it up and starts using it. Track your own loadout back through the dungeon and take it off whoever has it.
POCKET WORLDS TO EXPLORE
Between the fights there are small overworlds to wander through, each with its own little story. You can hunt for treasure, play mini-games and go fishing.
BRING IT ALL HOME
Rescued wisps move into the wings of your home island. The beds fill up and the residents get busy, and the garden slowly comes back to life. The longer you play, the more alive the old place gets.
