Bubble Blitz is a colour matching game I made based upon a game called Bubble Bomb, which I also published.
Bubble Bomb was originally written by another developer, but he had to stop making games because of conflict of interest with his day job so he gave me the source code. So, I published Bubble Bomb on Binary Sun, and I made my own version that you can see here.
The game is written in Blitz Basic a now discontinued game engine. I used to be really into Blitz Basic and made a lot of games and demos with it including Rocket Boards and ExGen.
