I made the checkpoint system last second. It saves your last position and your ship's last position when you collect the crystals. When you die it's meant to send you there. Did you collect the mask? It's meant to trigger the lava to go up and be an "epic chase sequence". But if you die it doesn't reset properly. The tiny things really added up to make this game just not work... sorry. When the jam's over I'll send you the updated version and I'd love for you to get the full experience. Thanks for playing.
