An update
After spending a little while yesterday lamenting how my first Ludum Dare had to have such a difficult theme, I composed myself and eventually settled on an idea. Using C as my programming language and SDL for tiles (and possibly sound, when I get around to it), I’m making a “mini-roguelike-like” game of sorts.
The gist of the game? Well, you’ll move around a small “dungeon” (which I hope to spice up a little) shooting, zapping, or bumping into robots to “kill” them in order to acquire their weapon and shield equipment. Every time a creature successfully attacks you, your shield will be weakened, until it finally runs out of power and a creature hits you and you die. And every time you attack a creature, your weapon will expend energy/ammunition until eventually it has none left.
Sounds a bit complicated and maybe a bit lame, but I hope to make it vaguely interesting: the trouble is, I’ve got less than a day left…
(Also, can I ask for clarification on one point: is it okay to use line-of-sight code—that I have full rights to—that I developed earlier for another game? Or is that against competition rules?)
