Nice little game with a lot of potential here! The UI is a bit 'frustrating' when dragging, as keys are immediately stored when hovering over them. Would be nice if only the "drop" would result in this actual drop (Hope you know what I mean). Puzzles are quite simple, which is why map design (in my opinion) needs some refinement. There does not have to be a maze when it clearly is not needed to guide your character through it :D
