FearLess Cheat Engine

Hello. I've been messing with the game taimanin collection and I've been able to change only highscores. Any idea on how to change gems (mainly) and other things? When I change anything other than highschores the game will restart. If someone can make a table I will appreciate it too.

+1, I too only able to messes with the score. I think this because its what they called by server side? hence we can't do for gems.
