I totally missed this somehow.
I wondered what Virtuous had been up to; they've done some solid work on Switch ports like Starlink and Dark Souls, but this looks to be on a whole other level so I'm very interested to see how it turns out. Apparently it's a UE4 game, and Switch has shown good results with this engine before, albeit usually at the cost of a lower resolution.
If it turns out well, I might even pick it up.
