Thanks for your reply.My phone's RAM is 8G.And i wana ask you one more question that how to tansfer savedata from my phone to PC? I can't find the savedata file in the phone. I really don't want to lose my savedata. I've working on it so much further.
That's not possible. However, if you make a bug report and then head to the Discord, I can extract the savefile from that bug report and send it to you.
