What is "kumoon"

Kumoon is a puzzle game that blends in third person shooter gameplay for Apple Macintosh and Microsoft Windows. It was developed in 2005 by Finnish programmer Mayoneez, also known as Mikko Oksalahti. The game uses the Mope physics engine developed by the same person. The game is getting a reboot for its ten-year anniversary, by Lucky You Studio. Featuring a full overhaul and VR support, the game was Greenlit in June.
