Hello, we are now in there too!
Our first ludum Dare Jam participation.
We are a team of two and use the following tools.
– Code: Delphi 7
– Type: SAI, GIMP, Pro Motion
– Sound: Bfxr, Audacity
– GFX API: OpenGL
– SFX API: Open-AL
For this event we’ll make a 2D game.  Built on homebrewn libraries.  Only for Windows… ;-(

Good luck and happy codeing

PS: maybe there will be a cross platform release, after some really good napping
