This game is very interesting and I think has potential to be very strategic. So far, I'm finding it necessary for my heroes to always advance all of the stats, the main challenge being deciding what order and getting a feel for how much is enough for a given level. If one hero gets stuck after losing too many challenges, the other gives you another chance to go rescue it, but otherwise I mainly stick to one hero if I manage to level it enough to complete the map.
Some ideas for further hero–hero interaction are as follows:
- When one hero beats a specific challenge type, it suppresses the difficulty of that challenge type by one level for one turn for the other hero. This lets a hero powerful in stat X help a hero weak in X if X is that hero's next step. Determining which hero to advance becomes a significant factor in bringing the heroes together.
- Given the above, it might make sense to have more than two heroes on a map, possibly with some totally isolated from the others (existing only for the purpose of helping other heroes beat specific challenges).
