This is an interesting story game for sure. It is very imaginative and intriguing, although I did find it a bit grim for my tastes. It is EXTREMELY linear and offers literally no gameplay at all other than looking around and walking slowly toward the next trigger, but for a game like this I don't think that is a bad thing.
My main criticism is that this game was weirdly similar to Gone Home in a bunch of ways. Like, all the subplots are very original and interesting, but the overall game is a walking simulator set in a creepy old empty house trying to figure out what happened to the people that lived there. The structure is so similar to Gone Home that after I read the summary after buying it and thought I had made a mistake and bought a game I had already played.

Obviously it was amazing in a lot of ways.  The new abilities are way more fun than BotW, the story is definitely stronger than BotW, the puzzle design is way better than BotW, the overworld design is much more interesting, there seems to me to be less useless filler.  Someone who likes open worlds will want to explore every inch of this place because it is so well done.
It definitely has some flaws as well though. Weather is perhaps explained slightly better but still sucks.  Rain and lightning especially are awful and add nothing to the game but frustration. Upgrading armor is a super important part of the game that is basically completely opaque.  The questline required to fully upgrade your armor might as well require searching on the internet.  There were a bunch of shrines that were "transport this crystal back to the shrine" quests that were sometimes fun but usually super tedious.
While the main land has been vastly improved, the added sky and depths areas are sorely lacking.  The sky area is great at first until you realize that it is mostly the exact same area copy pasted about 10 times.  The depths has some fun enemies / mini-bosses but is mostly a vast emptiness made worse by the annoying gloom mechanic and darkness requiring you to constantly throw or shoot little seeds to light up the way. Tediousness is not gameplay.
Some of the controls are weirdly clunky.  Trying to run or jump while crouched doesn't work until you uncrouch. You have to run to put away your weapon otherwise the shield button does nothing. There are a bunch of times I can no longer remember when I thought things should work one way and worked another instead.  Also, switching between powers was weirdly slow, I couldn't just push the power button and the direction and instantly get the new power.  I had to hold the power button for a half second until the power menu came up and THEN I could point a direction to switch powers.
The open world does not do any favors to the progression of the story.  Because you can do stuff in any order, they re-explain what is going on about 15 times.  There is one long major cinematic that is repeated almost verbatim 4 times in the game.  It is so identical it feels lazy.  I did a series of quests to get a bunch of background story and that ended up being basically a waste of time because all the interesting bits were called out later about 5 more times in other story parts.
Overall, highly recommended but definitely flawed.  If you like open world adventure games, it may be the best one ever made.  If not, ymmv.

Not for me. I like the idea behind all the color changing puzzles but ultimately the game just had a lot of stuff I didn't like.
The open world was super tedious with no map or good fast travel. The combat was terrible. The puzzles were occasionally fun and occasionally totally opaque. There were times when they would say "You have everything you need to solve this puzzle" for obvious puzzles and then there were puzzles which required leaps in logic of how various elements interacted with no such prompt.
For a mostly single developer labor of love, this is pretty incredible what was created. But for your time, I would spend it on other stuff.
