Awesome game! love the art and music. Simple fix when jumping next to the wall you get stuck. It is more than likely the ground collider mistaking the wall for the ground. Also Physic 2d could help.
Yeah, thanks, I'm sure we will be showing it off at the next LA Indie Dev Meetup, since three of us from the this meetup were on the team. I'm not sure if getting stuck on the walls is a feature or bug. There are other bug-ish things like this as well including what we like to call the Fox elevator.
