Very neatly polish tower defence game with a nice little bonus of having to constantly resupply your towers with ammo.
I do have to be a little harsh though because this fell into a lot of the traps that I feel really restricts tower defence games, the tower choices felt arbitrary, the enemies barely made it past the first corner but if they did it would have been an instant loss, the clicking mechanic while interesting at first quickly became mindless spamming and didn't end up adding anything to the gameplay.
Also I'm not really seeing much of the meta theme in the game at all.
It's on the verge of being a great, tower defence genre breaking game.
The balancing was very smooth though and it had really nice sprites and music.
