I loved the overall concept of the game. I felt like I was some demon lord summoning towers to protect my base, but the only problem with this kind of game is that later on when there are so many units, the game becomes really laggy. Not sure if there was an end, but I had like 30 towers haha
As a side, it would have been nice if the colors were a little more unique for the summoning tiles since the red overlapped with the towers so it was hard to see the color combinations.
