Great game and really polished considering the timeframe. I know this isn't the first Stencyl game by any means to do this, but it brings me a smile to see Box2D "tamed" into a really solid platforming engine - even the slopes feel natural.
Like Blob, I ran into the same dying bug, which happens if you die while the scene's still fading in. Can happen fairly easily if you walk off into the water by accident right after you respawn.
