OFF is a French roleplaying game by Mortis Ghost that has been translated to English. More info can be found in the forum thread for the translated game here. Details on version 3 of the translation can be found here.
In "OFF" you take control of a mysterious person called "The Batter", who is described to be on an important mission. The Batter, and yourself as his controller, are dropped off in zone 0, the first of 4 zones in a perplexing, unknown world about which you slowly find out more and more in the process of the game.

NOTE, RE: Mac Port: I have neither the technical expertise nor time to troubleshoot/support the Mac version that I've hastily created, sorry.
This is the game, don't move the file outside of the folder or it won't run. If you need to move the game elsewhere, move the entire folder named "OFF English 3.0.zip".
This application will contain your saves, try not to lose it.
Everything that was here was pretty outdated. It works now, probably.
