The size of game is 12 Gbytes.
To play on Android, see the instructions above on this page, under the heading “How to play on Android”.
Make sure you have more than 12 GB free on the device. The free space must be in the device/partition/directory you are downloading to.
The game can be downloaded from the main site and the external mirror site. Have you tried both?
Multiple parts, at best, means multiple zips that you will have to download, one by one in their entirety, to play the game once you are finished. PAR files, essentially, for those who are old enough to remember those, or Rxx files if you ever used RAR.
Separating the game into multiple single-character stories is simply unfeasible, partly because character stories are intertwined, which means you *will* need additional characters to continue a given character's storyline, but mostly because of the sheer amount of work it would entail.
