Here is my game. It is called I Never Missed Anyone Until The Were All Gone. It is not finished. But it is playable. There's not much to do though and it is very unpolished. And there's probably some glitches in there.

The game was made with C++ and uses the SDL, SDL_image and SDL_gfx libraries. The art was done by hand in pencil and was cleaned up in GIMP.

My idea was far too ambitious for one weekend, though I did manage to get a lot of the core game logic finished. Drawing my graphics by hand took far too long.

I plan to continue working on this in the future.
