Magnetis is a WiiWare and PC video game developed by Yullaby, and was released in 2009. The game is notably Yullaby's first independent project, after previously being commissioned to develop video games by third parties.
Despite its poor sales, Magnetis was generally met with good reviews. IGN UK gave the game a 7.5 (out of 10), praising its "slick presentation" and "deep mechanics", but said that the "lack of any online functionality was disappointing". Nintendo Life also gave it a similar score of 7 stars (out of 10), saying that "the music is possibly amongst the best you'll hear on WiiWare", but said there was a lack of variety in the gameplay.
