Lomando.com

lomando.com is a Japanese horror game, it's also called Fancy Island (Japanese: ふぁんしーあいらんど).

This website starts with a cute looking homepage explaining the game and that it is a horror game, after clicking the cat girls illustration they will get sent to a page where there is a door, after entering, they get sent to a page with an illustration of a girl, with a few dots/mirrors below the illustration, clicking these will send them to other pages which can branch out to several pages. After solving the mystery of each page, the player will finally be able to beat the final boss and complete the game. There are a lot of puzzles, mazes and different screamers on the website, mostly are totally unexpected. The game story is basically about heavy themes like paranoia, suicidal thoughts, and depression.

Gallery

NOTE: This page appears to be a normal gallery at first, but after a few seconds the gallery turns into some people with distorted faces. I believe this is the gallery they are talking about in the last square of the comic on how to play this game.
