It is pointless to forbid external files.. I could dump a file and embed it into my sourcecode, while I extract it on startup on disc. I would'nt wonder if there were entries with executables being ridiculous big because of embedded textures, music and so on.

I would'nt generally forbid this kind of stuff, but would add a maximum filesize for the executable, maybe max. 4 MB or something like this? Or is the Lite-C compiler restricting the max. size of executables?

If I would enter, I would do definitely something 3D related and since I have not the knowledge to generate sophisticated 3D meshes, I would dump them into my sourcecode. Textures, shader related images, heightmaps, particles, etc. instead, would I generate by my own algorithms. The same for music.
