This is honestly such a cute game, and I love the illustrations! I will definitely solo this once in a while going forward whenever I want to play something quick. I love the idea of skittering around as a little fairy and collecting crumbs of food.
My only real critique would be that the Mousehide Cowl and the Walnut Shell Mask seem redundant, or mechanically way too similar at least. Though I'm also not sure what else could you add that plays with the mechanics of the game, maybe finding two crumbs instead of one once per heist? I'm not sure.
