There is a fairly large demo of this available on the Eshop right now before it's launch tomorrow, the game does look absolutely beautiful on the Switch especially as a handheld title this is just gorgeous to look at and plays like a dream. Smooth as butter the whole way through the demo... only slight issue I had was a tech issue with the demo opening the eshop at the end where the system was still playing the game music while the shop was open and it did not run correctly at all. Also not sure if you can move your save from demo to retail game so it might be worth waiting the day if you know you're going to be buying this.
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
