I found a little typing mistake, I don't know if it has been reported yet.
The first gym leader says "Polémon" instead of "Pokémon" one time, after you defeated him.
Another thing I want to mention is the following: After you defeated the first gym leader, you get a call from the prof. But it's japanese and I didn't know that he said that I should get the egg from the market. So I had big problems to go on with the game. I spoke to every person but nothing happened, even after I talked to the guy in the market because my team was full so I wasn't able to get the egg. But I didn't realized that until I saw a walkthrough...
