Back in the day, my friends and I loved to rip a few games of Curve Fever 2. The original is gone and the game that took its place has objectionable aesthetic and gameplay tweaks.I've been working on making my dream "curve-like" game that captures the elegance of the original's gameplay while also allowing optional stuff like portals, rocket launchers, custom maps and modes like capture-the-flag. I'm kind of going for that sense of hilarity and semi-competitiveness of e.g. Halo 3 custom maps and modes.
My friends and I have been having a great time playing the initial version, and it's been fun working on some of the more interesting technical aspects like server + browser performance, mapping 2-d game space onto a 3-D visual space, etc. as well as some just-because-I-want to things like a dynamic music system.
