If you're just looking for a map that looks good for scrolling, wouldn't the sample project work well? Or are you thinking something more expansive?
I'm looking for something that would only require a little bit of additional work to turn into a cool-looking and possibly fun game playable on an iPad. Something to get someone's attention enough that they'll want to try the same thing.
Would it be possible to load a savegame via browser?
It would not be easy to load a savegame saved by a true SGDK2 game into an HTML5 version of the "game". And there are no save/load game features available for the HTML5 projects yet. But I expect there will be.
