As far as I have seen, the effect Fairy has been removed or something like that in v. 0.098i... Maybe has been moved to another place, but I don't know... I have gone to the Highway and I've seen the developers have opened some ways more, but they have removed this effect and the maze on the tunnel isn't there anymore... I hope they bring this ways back in the next version, because I don't understand how we can unlock the endings without the fairy effect.
If you know where to get the fairy effect at 0.098i, tell me please... Thank you :)
