After my talk with Adam he suggested I try marvel again (I used it for a dialogue prototype very early on).  So I made a Marvel project to show how the gameplay flow might work, navigating the map and completing the encounters that appear.

Building the Marvel prototype

The finished Marvel prototype shows how the player navigates the map, shows an example of a possible outcome (Combat), they player then playing and resolving that event and moving back to the map screen.
