Played about 45 minutes of this game on the PS5 (and briefly tried the PS4 version as well) and inital impressions are that it sure looks gorgeous, the tribal-influenced music is really excellent and adds a lot of atmosphere to the game. I'm playing in the 60 fps Performance mode and did notice a couple of framerate stutters. I also tried the 4K 30 fps Graphics mode but that just feels horrible after playing at 60 fps. The 4K/30 fps mode is only good for taking screenshots in my opinion and thankfully you can switch between both modes without having to restart the game (unlike Deathloop!). Incidentally, there's no mention of the Photo mode, which is accessed by pressing Up on the d-pad.
Not played enough to comment on the gameplay but what little I tried was fine. There's weak and strong attakcs on the R1 and R2 should buttons, you can dodge with circle and the game also has a lock-on system. It seems to play fine and the camera was generally good too at keeping everything in focus. Playing on Normal difficulty, I did manage to die once as respawning enemies attacked me while I was trying to use the Rots to clear an infected plant. I'm not saying that the game is hard, just that I wasn't paying proper attention to what I'd been told to do!
I also got a bit stuck at the first puzzle where you had to use the Rots to move a block to climb up into another area. I got distracted, looked away from the screen and missed the on-screen tutorial that explained the controls so it took me a few minutes to work out what the controls were (hold L2, points at where the block is to be moved to then press circle). Unfortunately, this game does not allow access to the tutorials from the Pause menu once they disappear - a silly oversight in my opinion and one I hoped will be fixed in a patch.
The only minor issue I have so far is that Kena herself is very quiet and doesn't comment on the surroundings as you explore. This in my opinion would help flesh her out as a character and give her more personality. It would also help explain the game world, what she is doing and what the various stones and shrines are that you encounter as you explore. This silent approach is a surprising oversight as the opening section has very little in the way of an introduction. There's no opening cinematic either, you get a screen of text that tells you about Spirit Guides then it just cuts straight to Kena in a cave. I thought there would be some kind of opening cinematic to set the scene?
Looking forward to playing this more later. This is exactly the kind of game that I enjoy and it does seem very promising from my brief play this morning.
