For those who have the crash problem at startup:
Try this, it worked for me:
First, uninstall the mod and install the original APK from the playstore, let the app download the resources, etc.
then complete the "tutorial"
(When you do 2 levels and die, let's say that you have everything free)
When you can open the settings and see your character, exit the game and install the mod.
PS: I have root and core patch, I don't know if installing the mod on other apps without root will work... in any case, try it and maybe it will work...
