This is a GENIUS idea for a game! I love the concept of guiding the spirits around the board to the glass. It was a real challenge trying to separate the good and bad spirits too.
I think it would be cool if it was hard to tell which spirits were good and which were bad. Maybe you could hint at the spirit's character and backstory so it's up to the player to decide which are allowed into the glass. Just a suggestion though.
Loved this entry! Very well done :)
