I can echo everyone here in saying the graphics of the game and the execution is fantastic. The keyboard controls on desktop and the thumb control on mobile works great. This got me very excited about the future! Can’t imagine the amount of effort that would have gone in this. One additional input, although I could play it well on the desktop - the mobile gameplay made me a tad nauseous. I am someone prone to nausea…
One thing I found is the field of view is much better in landscape orientation on my phone than portrait. Still a little small but not nearly as bad.
In fact, it's the best looking game experience on a foldable I've seen so far (most games are designed for either mobile or tablet form factor, and can't quite handle the in-between). And it's cool how you can just fold or unfold the device on the fly, and the game just adapts without anything more noticeable than the camera pivoting a bit if needed to keep the character on-screen. No stutter, no half-second pause for UI to realign, not even perspective change.
EDIT: I just realized it's probably not a mobile-specific thing, and sure enough, on a desktop you can just resize your browser window to see this.
