First time participant.
Will be writing the game in Linux, crosscompiling for Windows as well. Given a day or two extra, I’ll probably throw up a Mac OS X port, too (at least I hope to)…
I’m also working on my own ‘framework’-code, that helps me do basic stuff like sprite animation, tilemap rendering, collision detection, whatnot. This code contains its own binary format for tilemaps, tilesets, and sprite animations – and I also got some extremely ad-hoc editors to go along with this.
For music, if I get to that, I’ll probably make some beats with Hydrogen Drum Machine.
For graphics, I’ll use GIMP.
I haven’t figured out what to do with sound yet, so there’s a chance that my game will be silent – my ‘framework’ doesn’t yet have these things in place. But, still almost an entire week left, right?
I’ll also make a timelapse, using a small shellscript, imagemagick (for taking screenshots every 10 seconds), and mencoder for making this into a video.
