That’s strange because I receive a lot of message of friends who said that crash very often. It’s perhaps because they have old iOS device.
One issue I have on iOS only (not on Android) is the changing of scene (composer). You need a small delay (~50ms) before a change of scene on iOS, or else it will crash on iOS.
Thank you for your advice but it’s not my case I don’t use composer
I’ve tried a gain, playing for quite a while and I never crashed.
Thank you to tryed again.
I have receive more information. The game crash only on accelerate mode. It’s very strange 
For information I have 8500 download on android and 700 on IOS. There is a problem but I can’t find where it come from.
What do you mean by “accelerate mode”?

You can accelerate the game (you click on pause and on the “>>”) the game run 4 time faster. It work very well on android and windows(with more than 1000 characters) and it crash on ios with less than 40 characters on the map
What error are you getting?
