I participated in some past LD48s, my entry in the last one was called "Photon".
I'll probably use the Allegro library, maybe AllegroGL.
Got up really early, could only sleep for about 5 hours. Which may be bad, hopefully I'll not be tired all day. Now, idea huntings begins.
Desperatly trying to find an idea, I read this in the #ludumdare IRC channel:
<-- IrishRogue has quit (Quit: HydraIRC -> http://www.hydrairc.com <- IRC with a difference)
And all of a sudden, an idea started forming: '''Hydra'''. You play a small snake, who must eat, and therefore grows to a big Hydraw. So, ''growth'' will be the central part of the game. And it should be doable in 48h, being a simple 2D game.
Now, to start coding..
