Turning Towers

Solid game overall and the $1/pack is pretty reasonable to unlock the full game.

Only complaints are that towers will randomly "wander"/spin and are often looking in the wrong direction when enemies are coming. So these towers need to rotate around to attack, but some of them do it so slowly that enemies get through because your moron tower is off looking the wrong way. So frustrating and it's not something that the player can control.

You also can't set "preferred targets" for your towers as you can in similar games. The result is often seeing these slow turning towers "chasing" enemies while ignoring closer oncoming enemies. Again, this causes enemies to get through your tower range without being hurt significantly.

Dev, if you read this, turn off this "searching for enemies" action towers do when idle. Just have them face forward or let the player chose their resting direction. I'd also just increase the speed that flame/poison towers spin.

It's my favorite app, just needs a bug fix

It's challenging and lovely. My only complaint is that on the iPhone 7 I cannot pause my game. If I get stuck on a level I can't start over, I have to delete and re-download the app. Totally worth it though.

Super glad to see this game on IOS

Loved playing this on my pc in college. A fun tower defense with great theme. I'd buy the soundtrack if they let me :/

Hey devs, any chance you can restore purchases made on a windows device ? I'll prove I bought in to it by telling you going full rockets is OP
