I wasn't able to find any ghosts and using E at multiple angles at the vending machine didn't give me any ammo, but I'll definitely check back if there are updates - I'm a huge fan of the graphical style and the atmosphere.
You have to get ghost dust via the trash bins and then when you pick up the shotgun you can go to a vending machine and buy ammo from there. Then ghosts should spawn and they get faster each round. I will update this game sometime this week.
