I kind of forgot about this site, but it’s been getting a bit more traffic recently. A while ago I made a simple game that was the original idea of Ten Second War, but it had very little polish. I started working on a more feature complete web version soon after, but left it in an unfinished state for a long time, and only recently completed it.
Anyways, there is now a much more polished flash version of the game with more content and leaderboards.
