Crumple is an addictive little game about Enve, the envelope, who has found himself stuck in a dangerous paper factory that is slowly burning down! As a puzzle platformer, your head needs to be engaged and your fingers need to be active. As an episodic game, expect shorter more focused levels. Alongside the usual suite of movements and jumping, crumpling is key to success as the name might suggest. It's free and fun and well worth a go.
