Thank you for playing! The Sofa of Eternity is a juggernaut.
To be honest, I spent most of February bingeing the RE2 remake, and had Mr X in my head when designing the sofa's behaviour 😅 Like with him, the best play is usually to run, unless you are cornered.
Ah, it would have been good if I'd gotten some sort of warning about that. There was no sign that combat with the sofa was any different to the other enemy (which was pretty easy to kill, which implied that combat generally wasn't very dangerous), except when it was too late.
