Yes, there are plans for an iOS version! Godot has native support for iOS, so it should be pretty much plug-and-play. I haven't done it yet because of the developer fee that Apple charges, and because I am mainly an Android user myself. If there is enough interest though, I'm sure my partner would let me borrow her Macbook & iPad in order to bring this out though :)
They couldn't recapture the key reveal of the Matrix. It would be like doing a sequel to "The Sixth Sense"--tag line: "He's Still Dead". And without that, it's just another action movie except "bullet time" is no longer innovative.
Their solution was to go deeper into the mythology and the larger world, but that was never going to be as fresh as the original.
I would have done a time-jump and have Neo be the mentor figure to a new Neo (a Neo-Neo). They'd still be fighting the Architect (and maybe Smith) and they'd still explore the larger world of Zion + Machine City, but the key reveal would be that Neo himself is just a program (like the Oracle).
But what do I know? I'm just a simple programmer.
