The game is very entertaining but it crashes every 10 minutes on my Moto G 2gen & I have seen that many users have the same problem, even on devices with better specs!

It is necessary to improve the optimization of the game!

Yeah this is the first game that is crashing on my phone.

I am running it on a Nexus 7 2013 model and it started out fine. As my vault grows it crashes more and more. Now I'm lucky if I can play for 30 seconds before it crashes. My vault is pretty large right now, with lots of dwellers.
