Played it a week ago. I enjoyed all maps, and each had some unique quality to them. Can't comment in much detail after this time, though. Why this was released to be run as a mod is beyond me.
Demos
Breezeep: Theoretically a nice short romp, but apparently untested, because severe lack of ammo which makes gameplay frustrating.
Bloughsburgh: Proper E3M5 piece all around.
Tens: Oddly cute in a Sonic the Hedgehog sort of way.
NewHouse: Solid small map Bit green in places?
QMaster: Cool artistic/abstract architecture, bit of a geocomp vibe.
Shamblernaut: Bright, good trick with the fans.
S*****: Quality map, obvious heritage. End fight too little cover and too reliant on meticulous Quad timing.
