I really enjoyed the game! At first I didn't have much expectations, but then it was very fun to explore worlds, catch trains and meet strange characters. The atmosphere is surreal but also cute, I really like the design and the colours. The characters are very cute and different, they reminded me a bit of Miyazaki's animations. I found only an object near the lighthouse. I experienced 3 crashes with the trains (for example I was on the train and the second after I was on the rails. Also sometimes I got stuck with a dark screen when I entered the "dark" world with sea creatures).
It would be interesting to add more worlds, or to add more missions and goals, also to know more about the different "worlds" and the characters around ;)
