Well, what are your strength's?
Do you know any C? C++? Blitz Basic? The library you've provided is pretty neat, but how about something a bit more abstract? Any game's that don't use an engine or can turn a framework on it's head and add or change something to an engine or framework that shouldn't be possible with the options given?
I kinda ask this, not to be a pain in the @$$, but to see if you stand out better and maybe help you stand out to the community.
If you need an example of turning a framework on it's head; take 'The Way,' it's an RPG Maker 2000 game published ages ago by Crestfallen Studios. One of the feature's that framework/engine didn't have we're proper camera control's or scaling and that didn't get added for ease of use until RPG Maker XP. The Way had this feature included with script to include this feature and made the engine their own in some respect's.... Though this is just one rough example. You have anything that explores this in your example's?
