Weird, professor wasn't sleeping on my session (I started from the second to last chapter, maybe you've used some of your saves?).
Overall the update is very meh, technically there's a lot of new assets and animations but most of them suck. As with the nature of its new content. What's up with the old fags (professor), cringy jeet friend from the past, some enormous ugly chick, the art style tapered off hard in general. At the beginning the game's had such a nice, retro-like cozy look and feel and now it's basically gone.
