Okay, that fake ending on page 3 had me seeing flashbacks of the low sanity effects from Eternal Darkness.
Also, Shinichi's parents seem super-cool. Grown-up geeks that force their kid to play consoles with them? Oh woe!
Mako seems prone to saying dumb things because she's either nervous or gets too involved/emotionally pumped-up. Shinichi seems to say dumb things because he's Shinichi.
