ibb & 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. The game is focused on cooperative play and the two characters must work closely together to progress through the game. The intentionally lowercase names of ibb and obb come from the book The Well of Lost Plots by Jasper Fforde, where two "generics" with these names must earn their capital letters by evolving as characters.
