Curious about this requirement. I've already set up my github repo and submitted but why is it important that you're able to compile entries from scratch?
I'm worried that you won't be able to compile my game, just because it's a C++ project with dependencies (Chipmunk 2D for physics, SDL2/SDL_mixer/SDL_image for sound and graphics, etc.) and I'm cross-compiling it for Windows from Linux. Will you reach out if you have trouble building my game, or it just an instant disqualification?
