Music

In Smash Hit, the music refers to the soundtrack, that is seperate from the in-game sound effects, such as balls being thrown, glass breaking, metal falling, buttons being pressed, etc.

It can be customised on the "Options" menu.

Track List (on Bandcamp)
Checkpoint 6, Checkpoint 7, Endless and Versus/Co-Op have some significant errors in the music.

Role in Gameplay

 * Smash Hit's music is composed to be synchronized with the gameplay; for example, when Falling Glass Planks fall in Checkpoint 3 room 4 part 1 (second part is out of sync) you can hear a rumbling sound in the music.
 * When the tone changes to signal the beginning of stage 2 of Checkpoint 10, the speed increases by a large factor.
 * Checkpoint 10 stage 2 also shares a similar rhythm to Checkpoint 3 stage 4: overlap the CP3 stage 4 walkthrough with the CP10 stage 2 music, every time there is an abrupt change in tone, expect Falling Glass Planks to fall.

Other

 * The only time the music is used outside of any Mediocre game is a Roblox game known as Ultimate Marble Rider (this is because it contains Smash Hit music and that it mentions  Douglas Holmquist (who is the music composer)
