TD at its finest
Its a pretty awesome TD game, I enjoyed trying out different gem combinations and such, my fave has to be triple thunder. 9% chance to teleport the enemy back to the start of the maze? Yes please!
I have to agree with ShadowDragon8685 about the crappy fourth turret though, it deals 1000 damage, as opposed to the 961 of the third towers and it has longer range, but it fires much slower, has no special effects (well, besides the basic element effects) and costs a hell of a lot more, you could deffinately build a couple of teleport back to start turrets for the same price.
I give it 9, just so there is room for improvement.
