A brilliant, fantastically challenging puzzle game for veteran puzzle gamers. The level designers are freaking genius masterminds that never fail to stump you. These puzzles get really difficult while always looking simple on the surface, sorta like Snakebird. You know a puzzle game is great when you conclude that a level seems logically impossible, and then days later you decide to give it another shot, and a short time later you manage to solve it. This has happened to me multiple times now.

Such a well executed puzzle game. Simple concept on the surface, but can get really complex. The difficulty is great too. Some times you might get stuck thinking you tried everything, then you skip it and come back later (and your work is still there, which was a brilliant design move) and then you'll inevitably realize you needed to one small thing a little differently and bam, first try. 10/10

I like the game itself. But what baffles me is why you put the play button directly onto the puzzle field at the bottom center. You've got an entire lower right corner free. What invariably happens when placing track you'll start the train. This is awful design. Sometimes zooming out helps, but then placing tracks becomes more difficult. Move the play button and I'll change to a 5 star, which this game deserves. Maybe this isn't an issue on larger devices but on an S8 it's nearly game breaking
