I don't use Vgaga but :
Try to click on setting in the first screen (in the right corner) before to load the game.
The click on langage, and just go back on the main screen.
It worked for me before I switch my phone's language.
It's the only 2 tricks that I know
Thanks a lot!
For the next update, can you reduce the damage and def multiplier range?
1-10 is enough and will be more easy to choose than 1-100.
With love
