I have learned one very important thing from Loop: all games should have an ambient rain slider in their sound options. I’ll be contacting our John to get it on his next list. It is that most tranquil, serene of things and matches this simple puzzle game marvellously. You move hexagonal pieces around until lines of colour match up, flowing together in the titular loop. Developer John Cullen has deliberately included no elements that lead to a fail state or frustration, so you can go forever until you work each puzzle out. It’s not finished yet but you can play a demo of the first six levels.
