Sony's Santa Monica Studio, British developer Honeyslug and artist Richard Hogg have combined for an extraordinary collaborative piece of work with exceptional results – and not inconsiderable style and wit. Playing as a bizarre worm-like being, you have to thread your way through multiple worlds in an inter-dimensional game of hide and seek with your worm buddies. It's a questionable task because really the game has no explicit objective and is content to let you roam the world unhindered.

The minimalistic approach to design keeps everything simple, allowing the player to concentrate on exploration rather than mastering complex controls, while diving through mysterious portals leads to quirky landscapes reminiscent of the more trippy scenes from Yellow Submarine. Each of these new worlds is oddly endearing, ranging from surreal pool parties through floating oceans to coloured dot factories.

This genuinely feels like an adventure into the unknown, which is an achievement nowadays, although the non-linearity of Hohokum, while its biggest strength, can make the latter part of the game frustrating. It will doubtless perplex many players, but anyone open-minded and looking for something different will have a ball.
