Interesting game!
I was amazed by the cutscenes, the songs and the voice overs! The game has a great intro! I think this game has one of the best stories in this jam. Its clear to me that you invested some time in this and it really paid off.
The graphics are very good for a game that is 3d and doesn't take too much disk space
As a platformer fan, I found a little bit punishing that you can be killed by the lava when you time your jump wrong (sometimes i die in mid air just a little bit above the lava). It gets worse because you have to restart the level from the beginning, maybe a checkpoint could fix that.
