The version to read

Filing this under: kinetic-first half, branching-last third. The 5pb. releases across Xbox 360, PS3, PC, PS Vita, and iOS all ship the same script with tweaked tips; the 2014 JAST English release is the one to use if you're deciding between versions.

The anime is a faithful condensation of the true route but leaves the secondary heroines as background. If you watched it and bounced, the VN's expansion of Suzuha and Faris is the piece that was missing.
