Tower combination tech - Here they come!! (Patreon)

The zambies in Tower Girls will grow stronger, and so you'll have to keep up with damage! The way you upgrade your towers in Tower Girls is by combining the same tower type of the same level together. So to go from Level 1 to Level 2 you'll need to combine two level 1 towers together, the same for level 2 to level 3, etc.

Should be a fun mechanic.
