Thanks very much for your constructive feedback.
Once the jam is over we do plan to refine the game and complete it, and can address the problems you mentioned. But there are some bugs you had that I've not encountered, can I have some more feedback please?
1. Do you remember what you were doing before the game crashed? Or did it just appear random?
2. When the game over appears the spirit should die, were you still able to see the spirit? Or were you able to move the camera and the spirit wasn't visible?
Thanks again for playing.
