Really clever idea for a platformer. The little miner character is quite cute. Good job on making the jumping/platforming feel natural (a lot of jam games struggle with this). Had a couple times where the boulders collided with each other when it looked like they should have cleared each other, might need a pixel or two leeway so that when they do collide its clear they should have, though it didn't really impact my progress at all, more so a polish thing. Great job!
