Unique idea!
It was a bit confusing for me at first (cuz I'm dumb, lol!). After knowing that I have to use the opposite emotion of a bullet to shoot at the ghost I thought it would be easy, yet, it was actually quite challenging since the ghost will be shooting as well once they're connected to you. Spent a good amount of time to finally be good at the game. It's a pretty unique idea and I have to praise you for that. It must be a headache to code the bullets that will work on specific ghosts along with implementing the 'puzzle'. Well done for that, good job!
