A lot of times I know survival mode can get difficult and people will give up on their worlds, especially when they were doing well and got killed. Because of this, my minecraft app is cluttered with games I abandoned.
How far into the game do you usually go? For example, I tend to get to the part where ! have iron armor, tools and weapons and I have a decently large mine. At that point, I start getting overconfident. I go out to fight monsters and I get killed if I fall into a pool (killed by drowneds), Get hunted by a phantom, or if I get lost and have nowhere to go, eventually losing all my health and having to start all over again. Then... I rage quit.
