Nekogames' Underworld Trip is a platformer created in a style that is similar to Terry Cavanagh's Don't Look Back, where players will attempt to figure out what has happened to them by journeying deeper into the realm of the dead.

Throughout your adventure you will encounter numerous traps and obstacles which kills instantly on contact. There is no health system to allow for second chances, although you can restart from the beginning of a particular scene at any time with the use of the R key.

There are a total of eight stages to play and six single screen endings to discover, but you would have to replay the entire game starting with the first level in order to view another short end sequence. (ending requirements)
