This is my first Ludum Dare, ever! I’d like to think I work better under constraints, but I guess time (or lack thereof) will tell.
Maybe it won’t be that bad at all… Right?

My tools (so far):

Programming language: C (C99, via clang/gcc)
Developer platform: Linux (Ubuntu 13.10), port to Windows
Libraries: SDL2
Graphics: GIMP, Inkscape for 2D, (possibly) Blender for prototyping
Audio: Audacity, sfxr, maybe others
Other: Python for miscellaneous scripts
IDE: gedit and CMake.

EDIT, 11/28/2014: So I didn’t submit the game. I had it “done” in time, but couldn’t bundle the game as a standalone with all dependencies included. This is what I get for using repo dev packages. For what it’s worth, I put the source on GitHub: https://github.com/nukep/ludum28

My entry for #28 didn’t get submitted last year. Oh well, right?

Here’s take two. This time around, I’ll be using:

Language: Rust
Platform: Windows + eventual ports to OS X and Ubuntu
Libraries: SDL2 via the Rust SDL2 bindings, cgmath, my own OpenGL helper libraries
Graphics: OpenGL, likely 2.5D style. Photoshop/GIMP for raster, Flash for vector
Audio: Synthesized in-game, or bfxr/sfxr if it doesn’t work out
Editor: Atom

Rust is a formidable programming language. I’ve been extremely productive with it so far, so I hope that will be an advantage here. During development, I’ll stick with the same version of Rust nightly.

Yay!

EDIT (2014/12/03):
Graphics: Pyxel Edit and Tiled

Tileset is mostly done. They’ll likely be tweaked as I go on. Basic tile drawing is there, too.

The idea for my game is to have a screen-wrapping platformer (a la Mario Bros or Kid Icarus). Scrolling + wrapping will be used as a puzzle game mechanic (e.g. to kill enemies by crushing them against a wall).

I’ve been fighting a bit with OpenGL, but progress is good.
