One of the most fun puzzle games out there. The core concept is smart and it can be as relaxing or as difficult as you want (with pauses and speed controls.) You'll find yourself working on train timings and loop design. There are about 25 levels in all which are all pretty good. At the end of it you may find yourself wanting a tougher challenge and the DLC is there for that.

The only con is there is some RNG in that the next station to open up (or bridge, tunnel, etc.) is not clear. While it adds level variety which is very nice, this isn't a game that you'll be replaying 20 times, but maybe twice. What made it frustrating was that the variation and unpredictability made some challenges very hard to solve because your super smart solution that you figured out after the last try no longer works. Is it a deal breaker? No not at all. Is it frustrating to not have to do more than 10k damage and the trees this time around spawned so you can't build your loop without losing the challenge? Yes. But we are talking about 2 levels of the 25 where this was an issue.
