An open arena with a moat-surrounded low hill (you can get there from the ground, but not from the moat). Outer stairs lead to sniper perches... as the title implies, the emphasis is on spnkrs.

Another chisel-influenced level. Lots of concentric circles... with some neat flow in the center.

A big level, starting in a really dark room, with access to brighter areas. Some neat tricks, but the flooding one causes some nasty smearing... Also available in an Infinity flavor.

The first 5 levels of a purported 30 level scenario. Hard to say, since if you want the other 25 levels, you need to send money to the author... and these 5 just aren't good enough for that. Whatever... they'll give you a few minutes of blasting fun. (He really should learn about how to make doors look good in rooms taller than 1 wu...)
