Pyrozen, formerly known as Popbrain or webcypher, is a Canadian Adobe Flash game development team. The team was originally created by Chriss Martin and Jo The-luck, and has since added core members such as Yan Lepage and Vanbraun. Pyrozen first released Sift Heads in 2006(and made it one of the best-known Adobe Flash Games Ever) , and it went on to develop 138 games until 2014, when it stopped making Adobe Flash games. Since then, Chriss has developed games in other ways. His latest project is Sift Head Rush, which he developed on his own for 10 years in 2024.
