Another entry to the ongoing NeoFlash Summer Coding Competition 2007 just came in, titled PSP Tower Defense by TacticalPenguin. Like you would've guessed, it's a PSP version of the favorite desktop game complete with a level maker and other nifty features.

Unlike most tower defense games, TacticalPenguin has gone through all the trouble to allow players to customize their own challenge. Here are some gameplay factoids you'd want to know:

* creeps walk along the path trying to get to the other side
* they have a bar above them showing how much health they have left
* turrets can be built, sold (for half back), and upgraded to do more damage per shot
* info about the current wave is displayed at the bottom of the screen
* information about the turret the cursor is over and the turret type to build is displayed at the side of the screen
* the range of turrets is displayed by a circle around them
* money is used to buy turrets and upgrades for them
* when a creep gets through a life is lost; when all lives are lost the game is over
* everything can be customized to one's likings

The game itself is quite intuitive, though checking out the Readme file can do wonders. You may actually find something more interesting, and learn other sweet stuff you can do with the game.
