The contemplative puzzle game Prizma is the first game Carl designed and developed - he released it on itch.io in 2018. Players can rotate and position coloured cubes, and are tasked with recreating a particular shape to progress.

Prizma is peaceful and slow-paced, and encourages players to take their time exploring different combinations of colour and shape. Currently available for Mac and PC, Carl intends to develop a mobile version of Prizma in 2020.

Carl composed original music for Prizma’s soundtrack and trailer.
