1. Does Attack the Light or Unleash the Light have any permanently missable content (besides the mutually exclusive ending choice)?
2. Is there any promotional content in either of the games I mentioned?
3. Does either game have any bonuses for possessing save data from a different video game?
4. Is Unleash the Light identical on all platforms, including an in-game achievement system for those that lack it?
5. I've read that the Apple TV version of Attack the Light has extra content, does it have everything the mobile versions have or was anything cut/changed?
