Interesting concept! Pretty innovative and a great fit for the theme of the jam. The music was also really neat.
I had some trouble understanding the progression of the game. I knew I was supposed to collect resources but I had no in-game feedback of how I was doing. The meters top left didn't really seem to work the way I expected - collecting one type of resource made the others go down so I couldn't really top up all 3. Would be nice if there were intermediate stages for the player to reach. Maybe you have to collect 5 barrels of each resource to get to the next stage, where your jumps are bigger or your health is higher. And a visual indicator along with that to signify progress (maybe color change, or size/shape change). I also had some issues with navigating where sometimes I would jump off a rock and hit nothing and then fall back on that same rock.
Fun concept overall and could be really great with some tweaks!
