good stuff! I remember reading the original comic and I think it being in game form adds to the mental transformations, I like being able to observe things and having different responses depending on your IQ. hope it gets updated frequently and finished, but I remember the comic being like 500+ pages long so I can see it taking a while. only criticism I have is it's not super clear when you can/should be looking around for extra dialogue and when you're not allowed to, the game seems to have a lot of trial and error that isn't a big deal right now but I could see it adding up if it gets longer. I never found the porn in the preview icon and the few times I tried looking around I was met with "I shouldn't be doing this right now" so I kind of just gave up after a while.
that's a lot of negativity though for what I think is so far a promising VN. I think your mental degradation writing works super well for games and in the future I can see you potentially doing some interesting game design mechanics related to it. best of luck!
