Thank you very much, I'm glad to hear that you liked what you saw so far!
I'm very sorry, but at the moment there is no plan for a Pocket version, however you could play on it with an Everdrive or similar device.
About what's included in the Megapack, it's concretely this: the 2 ROMs with the full game (EN/JP), the OST in FLAC format and the comic in a PDF file.
Hope it helps you!
