There're some good mechanics going on here. I like the risk reward of sticking around to fight the ghosts for extra$ instead of leaving.
The variety in the ghosts is a nice touch since you could've got away with just 1.
There could be more sound and visual prompts to things you do as it wasn't 100% clear what you can steal and can't. Plus some ghosts spawned right in my path causing game over which is overpowered ghost move.
Overall cool concept, if you ever expand it multiple levels would be fun.
