Game crashe after changing the value more than 1

[OREW]

Hi,

Game name: Bloody ***** 

Google Play link: https://play.google.com/store/apps/details?id=com.tibith.badboxing

Is the game free? Yes!

 

I want to hack the level value to open all the classes 

But whenever i change it the game crashe!?

But! If i change the level by one 

Like 21  to 22 it's okay!

But if I want to open all the level the game crashe

The coins in other hands is same thing but the values is saved even after crashed 

I tried encrypted value search, X4 search, F,D, Double same thing 

Any help?
