It is purely a puzzle game with really nice graphic where you have to figure out the best way to connect all the industry/cities together. It is NOT a simulation game, I have no idea why Steam has it tagged that way.

There is currently 54 preset levels to solve in 8 different worlds and a random level generator so if you want to play more you can use that to generate levels up to your liking. Each world introduces a new mechanic/card, but however about halfway through the game it started feeling quite repetitive.

It has in my option a big flaw of not being able to see all the industry buildings from the beginning which makes it a bit hard to plan your railways making it a quite frustrating experience since you can not delete existing railways and while there is a reload checkpoint button it only works for a couple of moves. It definitely needs a proper undo.

That said, I still don't think it deserves a negative review and at the beginning it is quite enjoyable and satisfying, but I would not recommend buying it unless on a really steep discount or it is in a bundle as the price of 17,99€ feels very overpriced.

Works without any issues on Linux with Proton (9.0-4).
