Spewer is a 2009 browser-based puzzle-platform game. It uses liquid physics through regurgitation as its core mechanic. Taking the role of a mysterious test subject, code named "Spewer", the player must vomit their way through over 60 levels while learning new abilities, changing forms and piecing together their purpose in the game. It is also a part of The Basement Collection.
