My playtime is ~60 hours but it doesn't show on Steam because I played the itch.io version (which includes a Steam key).

You should play this game if you
- like this style of Sokoban puzzles.
- like games with knowledge gates and riddles like Tunic, Outer Wilds, or La-Mulana.
- don't get offended by nudity.
- don't get easily frustrated.

That last part seems important because the game asks a bit more of the player than a simple playthrough and also lacks a basic undo function, which is deliberate. Don't ask how I know.
But it's best if you go in blind, so maybe stop reading and just play it?

There are multiple routes, endings, and secrets to discover. Each expands a bit more on the puzzle mechanics with sub-dungeons with unique gimmicks and even boss fights. But if the thought of having to repeat sections of a game annoys you, then you won't get to see any of that. A first "normal" playthrough should take between 6 and 8 hours, and then you could just choose to quit. But this won't give you a satisfying ending. If you keep going, however, the game keeps on giving. It's surprising how much content there is.
The story also gets more confusing the farther you get. But at least the first two routes are relatively straight forward and cover topics like motherhood and what it's like to live with big boobs, which you don't see often in games. Has some slight Undertale vibes.

Now, if you'll excuse me, I'm going to listen to the soundtrack for the next 5 years.

One of the coolest gaming experiences I've ever played that I could never in good conscience recommend to someone. This game has a lot of intentionally frustrating design, and you'll be asking yourself "why would any dev do this" a lot. But if it didn't frustrate you and test your patience, it wouldn't be Void Stranger. The most important thing you need to play this game is patience. Don't be afraid to look up a spoiler-free guide or ask a friend for help if you're stuck-- the devs encourage it in the store page description.

Don't give up!

so god just buy it
