I also created a platformer-based game, but might is rather one-screen rooms than sidescrolling levels. Would love it if you could comment and rate it, especially since this is my first game jam entry. Thanks heaps!

Here is our jam. A 3d browser stealth puzzle game about eating sheep. Would have loved one more day to poliish levels and gameplay though! haha
