[1] Old School Musical: Pocket Edition, a version including only the Chicken Republic gamemode, was released for iOS and Android in 2019.

Old School Musical is a rhythm game in which the player must progress the main characters, Tib and Rob, through each level by correctly timing inputs.

Eventually, Tib and Rob visit a post-apocalyptic world known as Arckhania, where they find the tower and meet their mother on the top floor.

They travel to Cloche-Pied's world, where he shows them a temple with a mural depicting the two brothers as legendary heroes, destined to save the universe from a being called "the shadow".

After retrieving a magic key from an imprisoned elf in the Chicken Republic, Tib and Rob open the temple's portal to the Shadow World.

With the shadow gone and the glitches stopped, Tib and Rob decide to stay in the village in Cloche-Pied's world and enjoy their new, peaceful life.

Bertrand said "The idea was to make a rhythm game that is both fun to play and nice to watch", and he compared the original gameplay concept to the Project Diva series.

[5] MV Expo, a free DLC containing 5 new levels with music composed by Xavier Dang [fr], was released on June 25, 2020.

[7] Nintendo World Report gave the game a 7/10 rating and complimented the well-built gameplay, but criticized the music and story as being forgettable.

[10] A review published by Polygon found Old School Musical to be a "basic but fun" experience beyond its disordered retro game references.
