yesterday I played a very addictive game called something like tower defender on the phone of my girlfriend (HTC desire)

I would love to see this game come to the n900. or an instance of it. Maybe its allready out there but i couldnt find it.

The game is like this: the enemy has to move from the left to the right over the battle field. at start you can put some defend towers on the map. with every kill you get more money to buy new ones. The enemy cant destroy the towers but you need to keep them as long as possible on the battle field so they get enough damage to kill them. there are dozens of enemy types and defend towers types. Most towers can be upgraded in strenght multiple times, selled, or upgraded to other towers like mortars or anti air missile launchers.

At the picture below you can see the money. and the heart is the amount of enemies that you still can let pass before the game is finished.

Can some one make a port or is it allready to be downloaded?

here a picture of the game on the HTC:
