Nice prototype, addictive gameplay. Kudos!
Ward unlock screen can have a bit more love:
- When a first tier ward is highlighted, if I go down it shows the price for the last tier for the next row. I would expect it to show the same tier or the earliest one.
- The cost is a bit unreadable at first glance. Maybe add the essence icon next to it?
- For each row of a ward, Instead of radio buttons, it can be a progress bar or something in that sense that gives the "upgrading" feeling.
