Honestly, pretty good game.
However, I found a few issues with quality of life and gameplay. Here we go:
1. I had a lot of issues with deselecting the towers, so for much of the game I would have to play with a giant tower under my mouse
2. Halfway through the game, the enemies stacked up and seemed to be blocked by something, I don't know why. Screenshot included. If you zoom in, they seem to be all stacked on top of each other.
3. The starting up of the game is hard to beat, until you can afford rocket launchers, which are the most broken thing ever (not opposing the op rocket launchers, but it feels like the difficulty scales DOWN)
