There are plans for almost all of what you have commented :3
The plans are:
An adventure mode, in which you would play maps like this, and also some Spots of the map would be dialogs. Each Spot would have a possibility to unlock a brand new map to play. Also, each map would have very clear rewards in the form of Equipments and new cards. By the way, while writing this, I thought about Items, maybe potions. I'll think more about it.
I'm currently developing a menu that's gonna be accessible at the start of each map, in which the player is gonna be able to choose the cards that are going to be in his deck during the journey
