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 Code base was derived from a unpublished game which had the framework setup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!

After discovering that the game had an inefficient way of handling the turrets I have been able to increase performance of the game on the Xbox 360 which has always been a pain point in developing on XNA. I've also cleaned up the collision handling code and removed alot of excess calls that were not needed in the first place. I've also changed how the projectiles are rendered to make them more visible and crisper to the user, I used to do additive blend to make them more glowy, but the end resultas a bit blurrier and less defined outline that made them hard to see. I also made the background into a darker shade to make the ships seem more saturated/desaturated. I have also been tweaking with gameplay as I am trying to find the balance of making the game exciting at the first enemy versus easing in the player into the action. Overall though I am happy with the changes to the game both visually and techincally. However I am still unhappy with the gameplay. Here is a video of the latest changes:
