Silver Lining

This is a MVP of a concept I had. You play as a exorcist on a train with a briefcase cuffed to your hand as your weapon. Thankfully, the briefcase is lined with silver. On the train are passengers to meet and trade with. Conceptually for a full game it would have metroidvania-esque level design, to go with the trading. Instead, the prototype features a short level and an ability to get and trade for an upgrade.
