I've got a friend who no longer has access to a PC (just a Mac) and she really misses this old puzzle game called Flux. Its a fairly common type of block puzzler where you get a grid of colored blocks and you can detonate two or more touching blocks of the same color. The more you blow up at once, the bigger the score and no new blocks fall down from the top. Big points for totally clearing the screen. Sound familiar? She has access to most modern consoles and mac, but apperently emulators make her mac explode (or something like that). A web based version would work really well too. Implode and Sega Swirl are the only two I can think of for consoles, but the Turbo Duo and Dreamcast are a bit out of reach for my friend. Considering the huge variety of backwards compatible games for the GBA, Xbox and PS2 this thing has to be somewhere. Any ideas on other games that followed this paradigm?
