Each puzzle is reduced to the Vertex Cover problem, which is mathematically categorized as NP-complete. In other words, it is among the hardest problems in computer science. Fortunately the size of each puzzle is small enough to be solved realistically. 10/10 would recommend to my professor

About 25 puzzles in, the boards become a mishmash of symbols and directional arrows. There’s no overall pattern to decipher, just grunt guess-and-check work to find which magic button should be toggled first. Eventually, I just hit random buttons to see if I got lucky. Quit playing after several of those boards in a row.

I love games like this, and I find the difficulty progression very well paced. My only wish is that there were a minimum moves goal. Just so that there were more "puzzling". As of now, a bout a quarter of the levels lent themselves to deciphering the mechanics of the game, and some involved much more guess and check. Really great game, would reccommend.

So the game is so nice and the animations look clean. My only issue is that there’s no landscape mode playing for iPad and you can’t scroll through levels, so that means I can’t let my friends try the first couple levels without taking 5 minutes to go through levels. Other than that, I’m really enjoying it and it’s a fun thing to play when I’m bored. 😁

A really enjoyable, challenging and unique puzzle game. There seems to be a bug on level 29 though. Just like the other levels, I got all the buttons to display white but the game will not let me progress to the next level. App description says there are 50 levels...
