Ibb and Obb

ibb & obb is a puzzle-platform video game developed and published by Dutch company Sparpweed Games for the PlayStation 3. It began as Richard Boeser's graduation project and debuted at IndieCade in 2008. A port developed by Codeglue for Microsoft Windows was released in 2014, and the Nintendo Switch version was released on March 5, 2020, as Sparpweed's last release before its closure. The green creature, ibb, and the pink creature, obb, travel through a world divided by a thin horizon line; on either side of the barrier, everything is inverted and gravity works in opposite directions.
