Sonic Colors Ultimate debuted a few days ago ( here you can find our review of the PlayStation 4 version), but there are quite important problems with the Nintendo Switch version of the game. As reported by various users, this version of the game would present numerous bugs and glitches that would make Sonic Colors Ultimate almost unplayable on the Nintendo console.
A user on Twitter, for example, said he contacted Nintendo. The customer service agent he spoke to said that Nintendo is aware of the problem and gave the user a refund for the purchase made on Nintendo eShop. At the moment, there is still no official communication from Nintendo about it, so it depends on the customer service agent you come in contact with. Still, if the problem persists, Nintendo may officially express itself about it.
In short, if you want to try this return of Sonic Colors, the other versions of the game are certainly recommended, giving up portability, at least until the problems with the Nintendo Switch version are solved.
