Hi there!
After long silence here is the next update. Worked on to improve new dungeon map mechanics, it took some time, but I think it became very good. Last week I uploaded a gameplay video with it. With these developments the release date postponed to June, I am really sorry for it, but I try to bring the best from the game.
Here are some of the last week's new features:
Winter chapter level chooser and battle locations.
New hexa type: Vendor. You can trade items with him.
A new enemy: exploding bug. It will explode upon death or if it reach close enough to your heroes.
That's it for now, thanks for reading!
