There is only a .bsp file in your pk3. You have no references to shaders, to an .arena file, or to anything else. You might want to correct some of those things. Also, what gametypes does this map support? An .arena file tells that information. A .aas file is easy to make. Just throw your .bsp file into a .bspc output and it will generate an .aas (arena awareness system) file for you that bots can travel upon. There is much more to it than that, but the 1st part is to see if it will work. Since your .bsp is very light it will probably work on the Fun Server without causing crashes. But you should clean up your textures first. All in all, I like your starting product.
