That's really nice!!
I've been living in the objective c world for a while of late, but still get the mail from this project. I was pleased to see you using this as an introduction for game development. This was the library that I actually, finally, saw a game project completely through. Before, I would only dabble a bit, here and there, with the pieces of a game--or hack around in someone else's code--all the way back to allegro.c, id's doom engine, irlicht, ogre, etc.. I was always looking for that 'magic' tool that would make me a game programmer. Pulpcore had the straightforward api and approach that made it click for me.
So, best wishes with your courses.
