It's...going, I guess. Trying to get its libraries to work with languages besides its proprietary one was less simple than advertised, and progress has been slowed by sorta learning C++ at the same time, and class starting up again. Right now, I've gotten a first person controller and a room with a box. I figured I'd start with something as simple as possible while still being something I can be enthusiastic about and incorporate elements that will be valuable for more ambitious projects.
To that end, I've got plans for a Killing Floor type wave shooter thing, with plans for skill trees and randomized loot and stuff.
