I took a look at the source and demo apps, and it's a pretty minimal framework, providing only a few things and a series of conveniences that you won't get with pure SDL. Still, what it aims to do it does pretty well, you will just have to do lots of Model-side heavy lifting, as there's no collision code or other such handy things. I presume this is because many games could ask for many approaches to those problems.
