This is the best game I've seen so far in this jam, as evidenced by me playing it for about 30 mins to an hour
I'd say the cleansing spray should be a starting item, and that the inventory should be able to be scrolled through with z and c as well as the mouse wheel, but other than that, this game is just right!
I'd love to see this expanded into a roguelike with boss monsters and maybe even a balloon/character select!
