the sort of wandering survival. Generally this is the whole point.
Why creepers are scary.
They make no movesounds and you are walking through a mineshaft. you begin to go into a sort of daze, DIG DIG DIG, oh look zombie kill. Dig DIG DIG DIG, shit sand ok good avoided cave in. Dig dig, dig, man I have a lot of loot, dig dig dig. Don't have any food and this zombie flesh is all that is keeping me alive. DIG DIG DIG, one more daimond, dig digd gidididig SSSSSSSSSSSSSSSSSSSSSS BOOM! FUUUUUUUUUUUUUUUUUUUUCK.
It is sudden and loud, good chance that IRL you jumped in your chair.
LOLLOLOL DIG DIG DIG RAVINE AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH PLONK oh hi mr slime SSSSSSSSSSSSSSSSS BOOM! FUUUUUUUUUUUUUUUUUUU
That is creeper. It is a game which luls you into a sort of passive play state where you get relaxed and then BOOM. Yeah, sure you can hide in a hole but you won't. You'll get cocky or lazy and think pfft I got this shit.
