Supongo que si algun dia me lo compro entendere que tenga casi un 7, pero de momento es un5 y asi para mi.

Careful: it's addictive.

A very fun little puzzle game that starts out quite simple, but gets far more complex as it goes on with buildings blocking paths, stations being placed in odd areas and the little challenges becoming far more difficult to obtain, especially the "do not stop trains" one as that would always give you lots of options to be able to run multiple trains without them smashing into eachother or making you bankrupt.

I highly recommend it to any puzzle enthusiast out there.
