I think this map easily deserves an "excellent" rating, despite the fact that it's easy to get somewhat lost at places. It has a nice flow and great gameplay, and looks pretty good as well. Definitely a must-try!

Just replayed this after remembering that I never finished it before. Nice map. Kinda plain in places but you only really notice that if you force yourself to look. Overall style and details are very nice. Fun and original gameplay, no boring monster placements. Loved the lightning gun pickup and what happened right afterwards.

great map! i didn't even get lost.

Compared to digs01 and digs02, it's definitely more difficult - which is actually a good thing. More monsters, better design, (even) more fun. Many players love wind tunnels, and this offering does not disappoint in that aspect. You are getting blown all over the place and it's quite fun. I also have to praise balancing. You never run out of ammo, enemies are strategically placed, not unfairly, and challenge increases towards the end.
