I liked the music. Cool stuff! Interesting system. I wasn't quite sure how to get past the rock wall. though. I tried both ice and fire, so not sure if I missed an element or something. Mechanic seems like it could be interesting.
Thanks for playing! To get through the wall you need the air element that should be just above the spot where you encounter the wall. I do see how it could be a bit too hard to notice. Especially because it only spawns after you finish the tutorial with NPCs in the lower level.
