I can report a bug, after Crab battle, you can't go back and see what they said. Something is wrong. Don't know what.
The same when you play blackjack against Ty.. I think something is wrong with the code after playing either of them.
I don't really know much about the code, but maybe you should check how full the storage for the history is when you have played.
At least according to what I have read, so uses it something that save a bit of code (The text or choices you made) in a storage.
Let's say that you say 10 sentences gets saved to memory, when you go up to the 11 sentence it is still saving only 10. Because the first sentence is gone from memory. Is it something wrong with how it saves the memory after a "game".
After each time I have had to restart the whole game to get the back function to work again.
