There are numerous things in this map(s) that are just plain wrong.
Let´s start with the packaging: You should pack everything up so that the user just has to extract to /sauerbraten, not having to do all of it manually.
Use .mp3 or .ogg next time you add music.. (besides, it isn´t even played ?! Oo)
The thumbs.db file has nothing to do with sauerbraten, It´s a file generated and used by your image viewer.
The maps: Blocky, almost random architexture,cheap or default texturing. Large chunks simply unlit. Plus both haven´t been remipped. "bartoli" has 60 000 tris to be saved, and the other has an incredible 100 000 tris too much.
Plus, nothing has been carved away. Be sure you understand what you do.(read the txt-files in the sauer dir carefully!)
Performance, thus is unbearable. Fun therefore non exsistant on mediocre machines...
The default settings of the water look ugly and drag down performance as well.
Lavaball: I strongly suggest you learn the basics of making a map (not only the editing) in cube before you try to make sauerbraten maps.
Making a map isn´t only about making some rooms and putting monsters in. Textures and light serve certain purposes beyond making a wall visible..
I´d rate this one -3
P.S: Calling two maps a "map-pack" is a little exaggerated, don´t you think?
