I had a good time playing this! The music is really good and fitting

I found a rock that didn't go away and let me abuse that about 30 times before it finally despawned lol

oh also,  

the hitbox felt a bit strange at times, I also had times where my feet were not on the lava and I died because the guy was over the lava

Really cool implementation of the theme and the prerequisite! It was really well made but I would have like a bit more obvious feedback to confirm I'm actually destroying the lava rocks, like sound or effects unique to that interaction, but otherwise really well done and good luck with the Jam :)

Fun simple game I had fun. The controls felt good but sometimes Id break one of the lava orbs and it would go away other than that though really fun and quite difficult.

I think you need to upload the whole build folder as a zip file not just the exe because I can't play it.
