Net-Bubble is a game in the style of Puzzle Bubble, ported by Flavor. Release notes:

Here’s a new release with bug fixes, but I think it works fine (even the 2-player on the same machine). Honestly, I’m not really sure that I’m going to put any more work into it. I have started a new project that I think will be better. With Frozen Bubble out there and all the emulators that can play Puzzle Bobble / Bust-A-Move, I’m not sure that people would want to play this, anyway. If you want anything added, please feel free to ask me for the source code.Net-Bubble-gp2x_1-21-06_bin.zipProblems include: CPU AI is VERY slow, networking support removed, and no sound (see above)
