Hey, I intend to participate in LD21. I figured I’d drop in here and declare that. I don’t post a lot on the blog usually, but I hang out and babble all the time on the IRC channel #ludumdare on irc.afternet.org. I hope you’ll join me there.
I’m not completely decided on what tech I’m going to use, but I’m leaning towards C++ with SDL 1.3 and OpenGL. My other option would be AS3 with FlashPunk, which has some significant advantages of its own. Will probably depend on what sort of ideas I come up with once the theme is out.
