What should I add to Coinpurse Kobold?

I have received a lot of requests from people wanting to see Coinpurse Kobold developed into a full game, and I agree that it would be nice to see, I did not expect the reception to the game to be so warm!

I have some other ongoing projects I need to attend to (and actually cannot even attend to bugfixing until the judging period of the Gain Jam has concluded) but do plan on returning to this project at some point.

A very popular suggestion I've seen already is adding a way to distract people at a distance, whether by yipping, or spitting out a coin. Both were actually planned and partially implemented, but I couldn't get them working satisfactorily in time, so I opted to scrap them for the Jam version of the game.

Aside from bugfixes, more levels, and a proper story, what kind of things would people be interested in seeing added to the game?
