Free 3D MUGEN-ish fighting game engine EF-12 available now in English, 'change virtually any aspect' says creators

Very quick initial impressions make this feel something akin to Virtua Fighter or Tekken, but the developers have stated you can change virtually any aspect, so in theory you could make a 2D fighting game with 3D models, like Street Fighter 4.
This is a 443 MB download, and it's completely free if you want it to be. You can be playing/messing around with things seconds after you grab the .zip file. There's also a "pay what you want" pricing option available, if you want to financially contribute to this work.
If you like software like MUGEN, but want a more modern engine to play around with, this is a dream come true. Hit the jump to view their trailer.
