Nice game! I enjoyed playing it and it was interesting and tense :). Levels were original and unique, each providing it's own challenges. Art and music was fun and clean. Good job, one of the best games so far!
Some suggestions:
- Pause menu
- Maybe there needs to be indicator to know what track next train is coming. I know It makes it easier, thats why it's a maybe. Sometimes train coming from behind stopped train seems random and cannot be prevented, but some small lights on traffic stop to indicate it would be cool.
