There are some issues with the game

1. sometimes it freezes when I call save strings to write data to the sd card, which I do to store the scores in the game
2. if you push the menu button or the back button while playing the game starts from setup when you go back to it, and I was wondering if there was a way to pause it and have it pick up where it left off
3. when going back to the game after pressing the menu or back button it sometimes goes to a black screen and then crashes

Also I would like to make multiplayer modes for the game, which will be new ground for me.  If there are any developers interested in helping me with this and making the game a joint venture I'd be very happy! The source is here

1. void setup() {
2.   //  String[] lines = loadStrings("test.txt");
3. 
   
4.   println(dataPath(""));
5. }

2) Zooming in on the mouse coordinates only _sort of_ works if not used in conjunction with the center of screen zoom. By sort of I mean if I choose one spot on the screen to zoom towards and keep zooming on that spot, it works. However, if I zoom on one spot and then on another the second zoom will not zoom towards the second spot I've chosen. If I leave the third zoom in the same spot as the second zoom, the third zoom _will_ zoom in on the correct spot. So it's the change from one zoom location to another that's causing problems.
