As an experiment, this week I plan to release test changes to this mode for some subscription levels.
I want to convert the system into a card roguelike, increase the map size, give out new cards for battles and some objects on the map, add special "healing" buildings where you can restore health.
Leveling up outside of adventures will unlock new card options for dropping into adventures and improve some of the player's stats.
Let's see if this can change the current "boring" game cycle.
