My Tech Notes

Browser support: All major browsers except IE7 and earlier (interestingly, IE7 seems to have "canvas" element support, but it does not work at all as expected - not sure how this is even possible). IE8 and Firefox 3.6 work fine, but somewhat slower than Chrome, Safari, and Opera. Latest Chrome and Opera support the game perfectly.

Slow performance: There should be no problem playing this game on a modern computer in supported browser even in a full-screen mode; however, your mileage may vary, especially with older browsers or on poor hardware. In this case, you can modify default setting to decrease number of "ticks" and "redraw time", or make dimensions smaller (especially if you have a large screen). By playing with these parameters, I successfully made it work (even if not perfectly) on every system I tried so far.
