This release is basically 1:1 to the Steam release excluding some leftover debug files. If you want the definitive version, get this torrent of mine instead: https://sukebei.nyaa.si/view/4476322

The only benefit of this torrent is to have the official installer translated to English, Chinese and Japanese. You can in theory swap the files inside the folder oppai_ero_suc_academy with the ones from the previously mentioned torrent.

After literally 2 years, the knuckleheads at Frontwing released the game in JAST USA. Nothing more to say than that, because their release schedule leaves more questions than answers.
