Good submission! It would be nice if there was ammo indication. Also, if there were hotkeys to switch to specific turrets rather than cycling left and right things would flow much better.
Also, for what it's worth, there are many normal TDs (particularly within Warcraft 3, e.g. Gem TD, Element TD, Wintermaul, Wintermaul One etc) where you have control of the targeting from the turrets, so from my perspective this feels like a standard TD haha
