Flawed
The game doesnt tell you what enemies are going to take what path, so you set your turrets and the enemies don't even come close to them, its a trial and error thing. One entrance and one exit is all you need, don't over complicate things. Further, the turret's lack of constant damage made the game even worse. Also, the damn aliens that split into a bunch of tiny fast moving things are bullshit. Your turrets don't fire fast enough to hit them, and if the damage is low, the aliens don't die, and run out of range. All this stuff with mana and health regeneration is unnecessary. I know you were trying to be original, but that's very difficult, especially since TD games are so overdone.
