Too challenging.

Train Conductor is fun at first- I like the aesthetic, the animation and the complexity of the environments which change from day, to dusk, to night, to hazy, to rainy- but the game becomes ridiculously difficult the further you advance. Trains will appear on the tracks at an impossible rate which diminishes the games appeal. I like the element of challenge, but it needs to be reigned in a little bit because it takes away from the fun.
A game that seems to be designed for kids, but is really made for Mensa.
