Thanks a lot for the feedback! Yeah, we also wished we could do more with the map. We had so many ideas, but so little time to implement them. In case we decide to do a full release of this game, we would add a more dynamic approach, like Slay the Spire.
I'm glad you were able to figure out the battle gameplay! We also wondered if it would be too complicated, but we had fun making it and playing it too, so we left it in like it was.
