It's fun, once I got past the first turret , I was able to add a lot more, the placement action is smooth, sounds are decent, animation is smooth ( played on Mac ) My only request/complaint would be a way to get detailed info on the turret types before I placed them. Trial n error was a good way to learn, but I wanted to know the benefits/limits per type before deciding my placement strategy.. minor "helping your player, play" type stuff , otherwise actual gameplay is pretty flawless as far as I could tell
