Cute game! I really love the art. Like some other people mentioned, it would be great if there was music and sound effects. Also, if you plan to continue working on this it would be nice to have some way of getting around the map faster! (if there is already something like that, then I'm sorry I missed it)
Anyway, you may want to look into balancing the Grombit costume. I got so much candy once I put it on that it instantly destroyed the candy economy.
