Stable release, you say? Well, if you insist, but I'll have to withhold the New Enemy Editor until afterward*. Good thing I've been working on that backwards-compatability functionality, then!
EDIT1: (Who knows, maybe with this extra time I might be able to add 2x2 enemies. It's easier than it first appears...)
EDIT2: *Unless... nah.
EDIT3: Reinstated EDIT1. Why am I so dishonest?
