The monsters had been banished there by the humans a long time ago, so tension are always high when a human drops in to visit.
Undertale tells the story of a human child who falls into an underground cavern filled with horrible monsters and must find a way to escape back to the surface. Regardless of Undertale’s retro style, its soundtrack has timeless appeal and is great at evoking emotions. Outside of battle, music sets the appropriate mood, from the quirky jingle to somber melodies that build tension. These tracks put you on the edge of your seat as you try to fight or befriend your opponent. Each boss has its own theme song, which does a great job of enhancing the particular personality. Undertale's soundtrack is loaded with beautiful bit-based melodies which blend perfectly with the action on-screen. Every small detail reveals a deep understanding of its audience, which makes Undertale’s commentary on personhood incredibly effective. The game makes up for visual limitations with charming animations and excellent music.
However, it’s an incredibly expressive game from start to finish.
The graphics in Undertale aren’t always pretty, it’s often ugly, even.
