A 2-level solo map. Wow-this one's pretty impressive. The terms leave a little to be desired, but the author is Japanese, so be gentle. (They're at least understandable.) The level design, however... very, very nice. The last room will keep you busy for quite a while, unless you're a very adroit sidestepper. Classy use of solid transparent walls... If at any point, you feel lost, go back and check a previously sealed door, or broken switch. Also available from its own web page.
