   made a html5 game, polished it many many times▲211

   hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game.

You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

   Play abstract strategy board games online with friends or against bots▲180

   Thought I would post in celebration of 1 year of my website being online. I've been working on it on and off and currently the website allows users to play Hex, Tumbleweed, Amazons, and Connect 6 against friends or against practice bots. I've been a long time player of some of these games and I felt for a long time that the world could use a few more popular abstract strategy games compared to Chess or Go. If you try it, let me know what you think. I'm always looking for new games or new features to add :)
