As most other reviews have stated, you can enable "R-18" mode by just typing r18 at the main screen. However, not even NSFW content can save this game from being a nuisance to play.

--"Gameplay"--
This is pretty much the worst puzzle game I have ever played. Some pictures are too easy to solve, while others are just a nuisance of background pieces around the sky or grass. Although tedious, it was not hard in the slightest and as you saw the title of this review, the game can be beaten in 15-25 minutes.
Once you bring a puzzle piece out of the selection area, you cannot put the piece back, even if you want to so that you can put the correct piece there. You just have to use an empty space to put that unwanted piece. Major pet peeve of mine, and great oversight, especially in a self-proclaimed puzzle game!

--Art/Graphics--
Not the best NSFW content you can buy on Steam, it is cheap, and if you are looking for cheap R-18 games to play, this is for you.

--"Story"--
I played the game on the R-18 mode because why not, and I assumed this is how it is supposed to be played. So here's the true story of this terrible game.
There was a warrior that had a sword that looked like the blacksmith had their eyes closed and put metal together randomly. Said warrior was female and went into the cave pretty much without any clothes. So the goblins just kinda threw a rock at the sword and then swarmed her to have their way with her. I'm trying to avoid obvious words so that Steam cannot censor me. After that, a cat girl comes along and get trapped too(???). And then another not so well dressed female warrior comes along to save the day.
Or that's what I got from the 12, not 14, images that I had to piece together.

--Verdict--
Game's bad. Do not even buy it for the cheap H, just go to image boards or other sites to get yourself off for free. Or follow and donate to actually good artists on Twitter.

RATING: 2/10 - Effort was put into the game, but not enough.

Note: The other two images they are talking about are the "Game over" image and the "Credits" image. You actually have to put that together in the game as a puzzle right before the last image.

Thank you for reading my review. Have a nice day or evening!

Edit 1: Had to fix some formatting.

Edit 2: After refunded this monstrousity, my friend gifted the game to me.
