I forgot to fix the bug with the gem, currently it crashes the game if you break the gem after restarting. If you break it in one try it should work.
The shapes are ammo, currently the ice sword uses the mercury symbol. I need more in-game feedback to indicate that, I think a simple +10 Mercury (or sulphur, antimony, and zinc) would be a good start.
Bar under player health is gold/exp a la original dnd rules. Level ups don't do anything yet but will let you pick a power up between stages.
Anyways, thank you for the feedback! I'm glad you remembered my game.
