Strawberries

Is there a way to go back to get the strawberries? I saw the last two, but it was too late. I could not go back from the gate. I "finished" the game. Wanted to go back and get the strawberries to play the bonus chapter, but it started te game totally over. Any ideas? Thank you.

Looks like I may have found an answer. Well, maybe not an answer, but...Looks like the strawberry book is just a story. Not the bonus game play. Looks like the bonus game is unlocked after you complete the game. So, no need to find the other strawberries.

Yes you're right the bonus game is unlocked after finishing the regular game. All the strawberries do is unlock the strawberry book, if you'd like to read the story in that book.
