Ton of questions, I've been working on a small game (+engine) myself and it has been magnitudes more difficult than I imagined.

Do you have any blog posts about the process of making this? I see the technology link, but I'd like to hear a little more about the architecture. Something along the lines of a post mortem maybe.

* What sparked this idea?

* Was your initial set of features more simple or more complex?

* Any features you had to give up on?

* Any unexpected features you were able to add after you were forced to rearchitect it? (Ok, I may be painting my own experiences on you with this question.)

* How long did it take?
