Cute game,
The art is really nice.
I think it needs some in-game how-to (even tho it's easy and intuitive) so that players don't have to spam random keys to figure out what they can and can't do.
The companion is also nice but maybe give it some powers or a reason to be in the game, whether random heals, random attacks, etc.
all in all its a good jam submission, good job!
