New one for you!  This one has 14 new rooms, a new enemy with 4 variants, a bunch of improved weapons, and more.  "More" includes some bugfixes, as well as the start to a sound-effect-upgrade process.  The game is already rich with sound effects, but we (most specifically Craig, who is doing it) want it even bigger and better. More to come soon! Official forum thread on this post.
