MUJO is a decent casual puzzler with a pleasant aesthetic, but the total lack of effort made to bring the game in line with its new platform is deeply disappointing. The game's poorly optimised user interface and ill-fitting legacy in-app purchase system smack of a rush job. We've got no problem with developers bringing mobile games across to Switch. This is a portable system that's built on mobile technology, and there are plenty of top mobile games out there that would make for a good fit with just a little effort. MUJO, however, is a deeply lazy and cynical port.
