I am unable to rate it at this time because I can't actually get to a dungeon. I walk up to the driver seats and interact with them and all that happens is that a list of ITEM 1's is generated. Interacting with any of the items doesn't do anything.
First impression is that I like the setting. I like the backstory on the game page. The concept of having a vehicle as a home base (tradionally called a town screen) is great!
