Danny Baranowsky (Super Meat Boy, Crypt of the Necrodancer), Anamanaguchi (Scott Pilgrim vs. The World), C418 (Minecraft), Jim Guthrie (Superbrothers: Sword & Sworcery EP) and Kasson Crooker (FreQuency, Amplitude) will all contribute original music to the game should it reach its funding goal, Harmonix announced via Kickstarter update.
As of this writing, the campaign is just shy of $400,000 with a goal of $775,000. Harmonix has until 5 p.m. EST, May 23 to reach their goal. If the crowdfunding campaign fails, Harmonix has said that Amplitude will go "back on the shelf."
