This little game requires the Tcl plug-in, version 2.0. If you don't have it, take a look at a screenshot of Explode! in action and see what you're missing. Also, note that the program is about 70k long (mainly because of the fake window manager and lots of syntactic sugar that I stuck in there because I like syntactic sugar), so it might take a little while to load. You are highly advised to press the Help button before doing anything else. Note that this Tclet can also be run as a normal wish application, in which case the "windows" that appear in the Tclet are replaced by real windows on your screen.
