how can we upgrade spells and towers? they is some kind of mastery but I never get anything to improve it
Hi so in the live version of the game, the content is locked behind the demo. However, the system was outdated for a while (which is why it got pushed out of the demo) ... the visuals should not really be there.
We are working for a much more interesting overhaul of the mastery system for our next update that will be accessible in the demo :o
