Thanks guys. Hey if you're really REALLY bored, there's Rock, Paper, Scissors too. I also made Tic Tac Toe but the second player has to be sitting next to you. I didn't want to bog down the server with AI.
Sorry I forgot to mention, it's completely free. After december 11th it may require a (free) login account to upload scores but it only asks for an email address.
Sharko is a really addictive game I made for Windows (it's still in beta but it works really well). It's DX and C++. It's one of those swim around eat smaller fish until you grow larger and larger but I added an online scoreboard. I entered it into the IGF. I'll find out if I'm a finalist December 11th. Please excuse my attrocious web design; I'm a coder not an artist.
Thanks TCH, you guys rock!
