I need to cut the teeth from the beast but I found a way to get the Great Sword before the end of the intro. Now all I get is the message "you can't do that" when I try to cut the teeth out. How can I get past this problem?

Well, the developer of this game hardly is willing to address the game breaking problem reported since 2015.

Although, the game itself is quite nostalgic and beautiful - this is just the way of things as they are.


So, if you want the fastest solution - restart the game and avoid doing that. I know its cruel, but this is a realistic option.
