This game plays similarly to Binding of Isaac using game mechanics inspired by GhostBusters.
The game is well put together and plays cleanly. This includes the shop, which shows items when you sit in front of the table.
Be warned, neutralizing ghosts too quickly will cause them to drop their gold in an unreachable location. Not that you necessarily need the upgrades to win in this game, but they're nice to have.
A solid entry. Continue to jam, raise your ambitions, and you will grow.
