Evil update: I just finished HOME. Great game. As close as a successor to OFF a fangame could get story-wise. The combat system, though still not perfect, is leagues better than whatever OFF had to show. The game started off a bit wonky but it manages to keep on giving all the way through to the end, and it even has a nice true ending.
That being said, getting to it was a pain as I spent 3-4 hours trying to figure out what I did wrong only to realize that I answered a question incorrectly some ways back. Good thing I kept a save file for it, otherwise I don't think I could've sat through another 5 hours retracing my steps and recollecting everything-
Finished playing OFF and, well, I think my brain is still trying to process what I saw. Great game in terms of everything besides the combat. Basically a spam Z simulator and maybe the down key gets pressed every now and again.
