So this was fun! I definitely enjoyed the activatable ability mechanic, I think it adds something new to the incremental tower defense type game. I also enjoyed how easy it was to get powerful, usually very grindy skill trees bum me out. So well done, this is a solid base. My only feedback is there needs to be some more visual clarity. I only saw towards the end that there was a target amount of time to survive. Some of the sprites look more clear and crisp than others. And the boss could blend into the mob sometimes when they teleport. Very well done though, I had fun!
