An excellent start for your first game jam! The visuals and sound are all really well implemented (LOOOOOVE the parallax effect going on). Some of the mechanics are a bit clunky, the jump/physics in particular (though the walljump is really well implemented!). I also couldn't quite figure out where I was supposed to go, and I kept getting stuck with seemingly no way to get back, so I'd suggest making sure that you check that each path has a valid way forward/back.
