I decided to give the game's philiosphy a name. That is the Active Movement System, with this philosophy the player should never sit idle for long periods of time waiting for things to happen in a tower defense game. The player's direct involvement is crucial to winning the game. Having the player dynamically upgrade and pick up money are core components to the game. Also having certain nodes be movable adds another dimension to a already crowded tower defense genre.

After weeks of trying to find a name for my new tower defense game I have settled for the name Scribble Defense. I chose this name because the game reminds me of scribbles I made when I was younger. Mixing contrasting white lines on a black background, as well as having colorful towers to accentuate and add colors to the game.

Currently I added some new concepts to the game. First of all the game now supports 2 player co-op. Having two players in the game will increase the challenge level to account for the added player. Also I have added a money drop system, money no longer automatically add to the player's bank, but has to be picked up by either player to be added to the bank. This makes the game more dynamic as the player has to constantly move around in order to get money he needs to buy more towers.

General Thoughts:

1. This is my third game to be published on XBLIG
2. Code base was derived from a unpublished game which had the framework setup
3. I just wanted to create a simple shooter game
4. Attempted to do cross marketing between my games
5. Development time took 2 months

What went right:

1. Very fast development time because I knew I just wanted a simple dual stick shooter
2. The code base I have been using has been mature enough that I did not spend alot of time scratching my head
3. Simpler menus allowed me to concentrate on the gameplay better

What went wrong: 

1. The cross marketing seemed to have ticked some people off, even comparing my game to the Yaris game that came out of XBLA
2. The game was not quite as impossible during the first release, I had to fix gameplay for a patch but that probably hurt my sales
3. I did not try to innovate as much with this game to differentiate it from the dozens of twin stick shooters out there 

I recently put up the alpha version of Neo Terra Zune HD here. It is a simpler version of my Xbox game Neo Terra (Xbox.com).  You can download the game from here: Neo Terra Zune HD

My game Impossible Shoota has just been released on Xbox Live Indie Games for 80 ms pts. It is a straightforward dual stick shoota where you fight 500 enemies, and at the end you are rewarded with a game code for my other game Neo Terra!
