Glow development is progressing steadily. Like I told HopeDagger, I think it'll take about 10 minutes per level to beat. That's pretty substantial, and on top of that I've spec'd out the New Game+ and Survival modes for inclusion soon.
I'm also working on the props you'll need for the last level; lots of quest items and things to do. It'll be a more traditional fetch-quest RPG, and less with the blasting in the final map. Which is totally awesome.
More on this when I get back to my home PC. Damn, this game is going quite well.
