Etherborn

"Etherborn" looks visually stunning, but that’s about where the praise ends. The gravity-shifting mechanic is interesting at first, but the level design quickly becomes more frustrating than fun. The story tries to be deep and philosophical but comes off as vague and forgettable. It’s a short game, and yet, it still manages to overstay its welcome with slow pacing and awkward movement. Feels more like an artsy tech demo than a game you’d want to revisit.

The stuff that this game has is nice. The graphics are how they look on the cover, soundtrack is nice to listen to, and the puzzles are interesting and the main selling point of this game.
After beating the game there's a new game+ mode, which rearranges the location of some puzzle elements while keeping the same overall levels. I wasn't really interested in this part, but it's nice that the option is there.
There's technically a story in the game, but I didn't pay too much attention. The majority of the story comes in the force of a faceless narrator speaking at certain places in the game. The text felt like it was more intended to make me feel a certain emotion, than to tell me what was happening in the game, who I was, what the end goal of the game is.
Any downsides I feel about this game are minor. Some animations take time and are unskippable. Sometimes I wish I could move faster because I know where to go and how to get there, it just takes time for me to go all the way. Also you can rotate the camera in-place but you can't move the camera to observe your location from a different angle. In general this last point is not a problem because whenever you get to a new place you can just pause a second while the camera adjusts itself, I've only had one place where I wanted to see what was behind a wall but I couldn't. Also, I'm happy to say that I haven't been in any location where I soft-locked, so that's good.
Overall, I mildly recommend this game for puzzle enjoyers.

Cool perspective-based puzzle game!
Just right difficulty wise, short but sweet. You can finish the game + the "New Game+" in just about 4 hours.
Perfect for an evening/afternoon!

beautiful, understated and relaxing despite its challenging nature

This is one of greatest game runs beautifully on Steam Deck, highly recommended.

TLDR:
This is a fun game. But it is extremely short given it's price.
It took me ~2 hours to finish the game, and about the same time again to complete New Game+, which is the same levels but slightly different puzzle solutions.
It has great visuals, audio & atmosphere.
The puzzles are great, the controls & physics are intuitive.
They've even added auto-run and skippable cut-scenes for quality of life.
The "story" is terrible and irrelevant. It's just dialogue that you'll end up skipping over; it feels like it was tacked on.
So I did have fun, and enjoyed the game. But I played through the game and NG+ with all achievements in under 4 hours (despite what Steam says it took, due to playing offline on the Deck).
Worth a play, but definitely not at full price.

Short puzzle platformer that does not overstay it's welcome. The music is nice and relaxing to compliment the art style. Total play time is about 4 hours if you do new game +. Would recommend if you want a game to spend the afternoon with.
