Identify Forgot the name of this game, so I can't find it:

[MADKLLR]

I'm looking for a Dungeon crawler that happens in a castle-like place, female protagonist, dark blue hair, I think, a lot of outfits to change, side scroller, 2d pixelated style, pretty cool, once you "die" (lose) you don't actually 'game over' you go to a Prison

can someone help me?
