I historically gravitate toward puzzlers on mobile and I’m so glad I stumbled on this one. It may be one of the best I’ve ever played. Simple yet challenging and totally fun. I’m on world 4 after playing for one day. Each world has a new, different mechanic that keeps it interesting. The side challenges are quite difficult. I’ve only needed hints on two of them so far, which was after 15 min of trying each one. By the way, the hint system is perfect. The fact that hints can be activated is wonderful, which is why this game is leaps and bounds better than Cosmic Express. Plus getting a hint doesn’t really give the board away. It’s still challenging. Very well done Developer! Edit: I wrote this a little too soon. By world 5, similar to Cosmic Express, some levels get extremely difficult. The fun, quick puzzles turn into grinds of trial and error with large boards of ten+ pieces… guessing and checking with loops, passengers and train car timing. In several extra levels, I found myself googling the final solution, and realize I never would have gotten it. Most levels are quick, satisfying brain teasers. The large, complex ones aren’t so fun.
