yes, i removed it and got the toolbox, then i can escape, but i can't find a way to get to the fuse box back there... and then i'll get stuck and don't know where to progress);
also i replayed my save files today and find another strange thing that could be a bug? i saved in map screen before the story goes to basement part, and i find there's a gate location right next to it, but it gets really weird that this gate only appears in here one time, if i enter there and get out, or goes anywhere else and get out, the gate just disappears in the map screen. i wonder if it's designed to be like that, since i could'nt find a way to progress with my current items in there.
