This is part of the Two Weeks of Code.
Critical: an unfinished game, similar to many many others. Click or tap once to make a moving thing explode: after a little while, it does explode and starts (hopefully) a chain reaction of other things exploding near it, which then explode others, ad infinitum.
Unfinished primarily because I got bored with the idea of turning it into a real game; I wanted to experiment with making the moving things glow in some sensible way, with the jsGameSoup engine, and with audio in games, and did enough to prove to myself that that stuff was doable. Hooking up levels and scores and everything seemed too much like hard work, since the idea itself wasn’t particularly innovative. :-)
