Love the project 100%! Keep it up!
Some ideas for future updates:
- Some sort of mechanic to prevent dawdling/Grinding - being able to spend time to remove the "Fog of War" to plan a route completely removes the purpose of it and allows a player to beat all the enemies and visit the shop when they think it's wise. EG. Ghost from Spelunky.
(If this idea is followed, I think 1 shop per floor would be wiser, so players have to decide if they can spare time to visit the shop)
- More risk reward in cards and "Talismans"/"Traits"?
