As far as I can remember the mobile port of Jet Set Willy never managed to make it out into the wild and that’s a big shame as it’s quite a gorgeous looking thing. Whilst it no doubt would have been quite the handful to try and play the game on a normal mobile phone screen from the time (we’re talking 2004 here, long before smartphones were AThingTM) it was none the less, a really lovely recreation of the game that played great and sounded great too.
Numfun would later go on to write the final “official” entry into the Willy series with… Jet Set Racing which is, yes, a kart racer. You may laugh but it’s a really nice Kart Racer as mobile phone games from 2005 Kart Racing style go. And we get to find out the foot is called Terry. So that’s a thing.
Anyway, here’s some “look what you could have won” pictures of the game.
