Love it!
The graphics are very cool, the gameplay is simple to grasp but very quickly challenging, the music is on point.
Found a weird issue where I had 2 towers one below the other, and I couldn't upgrade the top one as when clicking on upgrade it was always counting as if I was clicking on the lower tower and made me focus it instead.
Also it would be nice to have a bit more time to prepare when the terrain switches.
But overall I had a great time playing it! Very well done!
