For a puzzle game, it does meet the basics requirements for me to play it long enough to enjoy it and write this review.
In Pleasure Puzzle. you can choose from a 6 piece set-up, up to 100 piece set-up for about 100 different portrait photos (hence the title name). They're all basically a collage of selfies, posters, cards, and other means that one can obtain a portrait in today's modern society. All these AI looking images was good for a play or two, but I found myself getting bored very easily.
The achievements aren't difficult, but very tedious. You can also repeat the same puzzle difficulty to increase the puzzle score. There's the options to exit, adjust screen and exit the game as shown on the top right of the screen, but it's unclear which button does what. There's no tutorial nor instructions. You also can move the pieces from any location, they do't need to be side-by-side.
Music is relaxing, and I think there's a 3-4 song list played on a loop indefinitely. However, it got boring really fast, and I ended up muting it to play my own music.
Overall, it's worth playing if you want a casual, puzzle game with no real challenge. For me, it was a rather dull game. but for someone else, Pleasure Puzzle may be the game for you.
