We're a bunch of nerds working on Noita in Helsinki.
Petri Purho is best known as the creator of Crayon Physics Deluxe. In his youth he also made a lot tiny freeware games. He has also made a bunch of board games, but he hasn't told about it to anyone. So please keep it a secret. Hopefully he'll get around to uploading them to itch.
Olli Harjola released his first commercial game The Swapper in 2013. Besides indie games, he also dabbles in music, live visuals and making programming languages.
Arvi Teikari is also known as Hempuli. Now probably best know as the creator of Baba Is You. But over the years he has released a lot of tiny experimental games, so many in fact that he doesn't remember all of them.
