And why android version is only 1.1.7
The game definitely has content from 1.4.3 like new game plus and the new cut-ins, but I am unsure if any feature was left out during the porting process.
To explain why the version numbers aren't the same. It is because HBOX a different company handles the android version and by that point 1.4 update was already out. Porting the game to android wasnt just a copy and paste job though as I believe the game was ported over to RPGMaker from WolfEngine(that's why the game doesnt appear 1 to 1 in UI). Android therefore has a different set of bugfixes and so different version numbers, think of it as a different branch that started from 1.4 but labeled as version 1.
Version numbers rarely even matters for laypeople anyway.
