Yes, Maze Manor was made with C2, and yes, appmobi gives a speed boost. It's about 5x faster. I've only tested on my droid. I'm not sure about IOS yet. I only have an old ipod touch designated as a developer device, and I'm sure my app won't run on it(even with a speed boost). That's why I'm excited about mobiOne at least I can test on my non-designated iphone4. Although without appmobi's speed boost I'm not sure it will run good anyway.
