In general, a nice, simple game, with a soothing soundtrack and good enough minimalistic graphics.
The main set of rules is pretty simple, you need to connect different "pieces" of the puzzle by inserting them in the right positions on a hexagonal grid, such that every "leg" coming out of a piece has an unobstructed path to a "leg" of the same type. This kind of simple puzzle concept tends to make for some pretty interesting mental challenges, and this game is no different in that respect.
The levels are rather hard, right from the get go. This isn't necessarily a bad thing, but may be a little bit alienating for more, so to say, "casual" players. On the other hand, it's a very worthwhile challenge for, so to say, "seasoned veterans" in this kind of logic puzzle game. I don't claim to be in either of these two groups, but I still enjoyed this game.
I'd recommend it for people who are absolute fans of logic puzzles.
