Oh man... I have just wasted 20 minutes by playing this map. The only purpose I can imagine for
it is to use it as sniping practiser against bots.

To the author:

These reviews serve at least two purposes; they give the downloaders as unbiased information
on maps as possible and then they may give some advice to the mappers.

My advice for You is to keep on going but try to make smaller maps with some idea in them.
If I had enough skills I had made several maps with Finnish culture content.... One of them would
be our sauna. The map I just reviewed has no such content. It is just a huge cube with some smaller
geometric shapes inside it. Nali City has a forum for this kind of stuff in case You lack ideas.
I really wish You would spend more time with fewer maps.
