Adventure / Point-and-Click / Narrative Games

It is, but there are a lot of twists though that I enjoyed. It's one of those "figure the rules out by yourself" kind of puzzle that makes it fun. It doesn't have many actions though.

In the reviews, people basically say that if the type of puzzle interests you, then you'll probably like the game. It doesn't really matter if it's the same puzzle if it's well executed, varies from its basic concept, and satisfying to solve.

Some people play crosswords every day and buy books and books of them. Some people think they're annoying. I probably won't buy this game, but if I did like this kind of puzzle - there's 500 of them there! For 37?? That's value!

This has only one type of puzzle that is repeated over and over again?

Not exactly. There's a basic idea underlying the puzzles (click on a circle and draw a line to the end point) but the game takes that trivial mechanic and really pushes it as far as it can. The game doesn't explicitly tell you what the symbols on the boards mean -- you have to infer that yourself through experimentation to figure out valid solutions with puzzle sequences to help you grasp an idea. The game is basically a giant meditation on observation/perspective/inference/the scientific method/learning/etc. If that sounds intriguing, you might like the game; if that sounds pretentious and annoying, you probably won't.

To the game's credit, it has some genuinely neat ideas. I strongly advise not looking anything up about the game if you think you might enjoy playing it. It's a game about discovery and some of the more interesting epiphanies you can have are easily spoiled...

And they want 37€ for this?

I got it for ~$10 from GOG a few years ago when it was on sale. 37€ is basically the launch price from almost a decade ago.
