• Added a real player two paddle.

Build 0.1.7 December 31, 2007

• Added the score numbers in Lucida Sans Unicode. It sounds like the most boring font but think that works for this game. Our art director may change this later. Also hooked the actual scores up to the sprites.
• Finally detecting lid closes.

Build 0.1.6 November 30, 2007

• The ball can now move between screens. There are actually two balls, one for each graphics engine. However, only the main ball (lower screen) is checked checked for collision detection. The sprites in each screen will wrap and currently using this feature to draw the ball on the top screen when the position goes negative. The same goes for the top paddle so didn't have to rewrite physics methods at all. Forced paddle to be in negative world (yes, that was a Mario reference) so that the negative world ball will collide with it.
• The ball can travel through the goal. It is keeping a score up to 9 but you can't see it yet.

Build 0.1.4 October 31, 2007

• A paddle appears when you touch the bottom screen. You can move it around. If you're not moving too fast, the ball will sort of bounce off of it. That is all. Might leave the physics as bad as it is for now and concentrate on sending the ball to both screens next.
• Added paddle sprite.
• Hooked paddle sprite up to touch screen input.
• Added some simple collision detection.

Build 0.1.3 September 30, 2007

• This Build actually looks worse than the last one. Dropping pretty pictures for functionality. Wanted to learn how to use the 2D graphics engines in graphics mode so drew parts of the neon bars and the ball using a simple 16-color palette. It is now displaying the backgrounds and ball (finally a moving ball) using character and screen data however, the game is still not playable. For people without a hardware setup, bundling NO$GBA (a Nintendo DS emulator) with this release.
• Removed full color bitmap image to allow using graphics mode.
• Learned how to use 16x16 color palette.
• Added character background for glow.
• Added character background for neon.
• Added spinning ball sprite.

Build 0.1.1 August 31, 2007

• Grabbed one side of the board from Wii Play and converted it to a DS-sized screen. It uses both 2D engines to display the screen on the upper and lower screen. The code from June release was not really how it was intended to be implemented the paddle so it is not included in this Build . In other words, this Build just puts a picture on each screen.
