Thanks! It depends on how you define easter egg, but there are a number of things in the game that are somewhat more obscure. Have you found the keys yet, for example? Or the Street Sausage? And there's actually one reference not a single person has commented on yet. None of this is essential of course, but there are some minor things hidden here and there.
ive yet to find the street sausage,though i would love more stuff with the thing that happened in the side alley~,you know the one where the person disappeared?,dont want to get too descript for people so not spoil
but yeah maybe the dogs perverted the graffiti in the entertainment district,and have it so each one mezz finds puts him more and more into a hypno slut mode more or such,fun stuff like that
