Haha, so exactly the opposite of Darkjeeling, who didn't like the swinging levels. Yeah, I'd love to make a whole set of levels about swinging another object around (maybe even with the path-follower being invulnerable or having no collisions). It's a neat mechanic once you start figuring out how to use it.
Re: you making the game: it's in LOVE2D (Lua-based 2D game engine), so you can probably unzip the .exe to find the source files (I know 7-zip will do it, but probably other zip utilities will as well?). We didn't open-source it, but personal use falls under fair-use AFAIK. Post-jam I'd love to build a level editor. The paths are just Bezier curves so that would be fairly easy.
Do you have a game in the jam?
