This game came out of my mind 20 years ago thanks to the great platform that were HP 48 calculators (I've had 3 of them). I loved playing Puzzle Bobble, Tetris and other casual game on my HP, but was also eager to develop my own game (a sily habit I have to develop games to discover new platforms/languages), and came with this idea of a kind of mashup of Puzzle Bobble and other games.

I never found a satisfying name for this game, so I now took "esviji", a word game on "SVG", the technology used for its development.

esviji is open source, under MIT licence, feel free to fork it on Github, make pull requests and open issues for bugs and improvement ideas.
