Squirm.io — free multiplayer worm game Play free

Credits

Squirm.io is built on work other people gave away. These are the Squirm.io credits: every music track in the game, who made it, and where it came from.

The theme is released under CC0 1.0, which places it in the public domain and asks for nothing in return, and the in-game songs were made for Squirm.io. The Halloween Party's songs are by DavidKBD and Kevin MacLeod under Creative Commons Attribution 4.0, credited below in the words their licences ask for. We list every track, because someone wrote each of these and the game is better for it.

Music

Soundtrack

The Squirm theme, on loop.

In-game

Squirm's own songs, the same for everyone.

Wind Down

Slow, calm songs for the Wind Down theme.

Rain

Quiet rain under the Wind Down songs.

Sound effects

The everyday sound effects in Squirm.io are CC0 1.0, from three people. Like the music, no attribution is required and it is here anyway.
