Honestly? Not the worst game I've played today. The all-grey, pencil-drawn look is a strong choice. I don't think it works here, but it's a cool idea. Maybe with higher-res images and cleaner line work? You've got the building blocks of an RPG all set up--I actually really liked the combat screen. I think the idea of a minor enemy collecting XP and going on an adventure could totally work.
It's a shame you didn't have more time to work on this--I would have liked to see more.
