No jokes, Innsmouth Case is a really good interactive fiction/visual novel/whatever you want to call it game. Its a very funny game (especially if you've read Lovecraft yourself) with some spooky bits here and there, a great visual style, and lots of paths/endings to discover. Same devs also made Plan B From Outer Space, which you should also get; its like this game but aliens instead of fishmen.
