Like another review has said, there are plenty of typos. I have run into a different issue, the game broke after the puzzle with the train. The next puzzle didn't load, and I had an issue with a previous one not loading either. Very frustrating.
I started playing this game and I thought I really found a game with a lot of potential. But then I came to the boy building a sandcastle. Beach was a six letter word and Building was so misspelled that I had to use all the hints because I didn't even recognize the word.
