lomando.com is a Japanese screamer website, it is also called as "Fancy Island" ( ふぁんしーあいらんど ). This website starts being cute and normal, but when you click the cat girl image with the site's logo, you will be redirected to the same site, but now it has black background and a picture of a woman staring at the viewer. When you click on the image, a ghost will pop up and run up to the screen along with a scream/moan.

This site strangely contains a story, and when you go deeply to it, you will fight the final boss and finally complete the "game". There's 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. It can be listed as "Utsu ge"(Utsu ge means "depressing game". The purpose of these types of games is to depress the player) or just as a typical horror game.
