Are you being plagued by grid based defense games? Too many turrets and monsters littering your flash desktop? Well help is on the way!

Yes! Crystal Defenders, a grid based defense game on the iPhone! The antithesis to it all!

Oh wait - no it isn't, it's basically just a normal turret game, with Square FF type designs plastered over the top and some pretty good animations and music. How lazy is that eh?

Well not very it turns out, frankly the game is fantastic - it borrows the usual structure of a turret game, and then adds to it with some very creative units - powerup crystals and an astounding game balance that overall create a surprisingly deep and rewarding experience. I mean heck, I've played - and got bored of, most of the big flash based defense games, but this is something else.

So fiendishly addictive that i have taken to bringing it with me when i go for a crap - and spent so long on it that i've actually had the opportunity to both crap twice and get numb legs.

It is a great game - and if it causes me to one day drop my beloved iPhone down the crapper, then so be it.
