If I was shown this with no context, I would think this is a 20$ game demo instead of a game jam game! Everything is insanely polished, I can't believe you made all the assets from scratch. It's a visually stunning game. I had some frustration with the resource system and almost soft-locked the game because I had died a couple times getting resources back to the boat, and there were barely enough resources for me to get the grappling hook. It would have been nice to get a couple extra seconds of time when the oxygen ran out. Besides the skill issue, all the other mechanics were satisfying (especially the grappling hook). The team did great work on this one, surely you're pushing for a commercial release right?
