Undertale

Undertale is video game created by Toby Fox, released on the 15th September 2015. Its players control a child who has fallen into the Underground, another world which is placed under the surface of the Earth and it is separated from our world by a magic barrier. The player meets many characthers to return to the surface and can choose to fight them through the combat system or he can spare them, in some other ways. These choices affect the game and its outcome.
The entire music is composed by Toby Fox.
