I've been working on Ejecta[1] in the past few month. If you want to publish your game on the iPhone/iPad, this could be interesting to you. I'd love to know if (and how well) it works with your game.
I am curious about your javascript integration with the app. Did you use V8 internally with some kind of bridging for Objective-C ? It would be great if you have a blog on the subject. Thanks.
Since you already went to the work of implementing everything from scratch anyway, is there a reason that you don't compile the code up front?
My understanding was that the big bottleneck for Javascript on iOS was the inability to use JIT (due to the lack of execute support for code on the stack or heap) and this seems like the perfect opportunity to bypass that issue entirely.
