I'm a sucker for tower defense games, and I honestly LOVE this concept. For a game like this though I personally would like even more control; either being able to shoot/target stuff myself or choosing when to drop a new turret, where if I wait then the turret becomes bigger upon being dropped maybe?
Either way, a solid 8/10 from me. The visuals are simplistic enough to be enjoyable but the sounds get *slightly* annoying after a while, but it could definitely be a lot worse. The music is great though!
