The v1.6 update will be submitted to the marketplace on this coming monday. Meanwhile I’ve added a few new improvements related to how the Tower Upgrades work. While most of them are based on improving the workflow under the hood, the tower stats menu is also getting a new sweet visual upgrade. 
Instead of the v1.5 menu which just shows the existing stats & upgrade cost, the new stats menu will show upgraded stats alongside existing stats.
