If a boulder falls on top of you, you die, and if you try to run from it, it chases you and you still die. If you fall into lava, you die. If you drop a voodoo doll into the lava, by complete accident.... you. are. screwed. If you're mining sand, and it starts falling on you, you suffocate. If you're looking for hearts in the underground to max out your life, you'll get stuck in a cobweb, and a dart trap will kill you. So you go back, and you see a gold chest. Right as you are about to loot it, you forget to look up and a boulder smashes you. If you forget to bring glowsticks and are stuck underwater, you won't be able to breathe and you'll drown. If you're just exploring the world from left to right, you suddenly realize that everything turns red. You keep going, only to be surrounded by a barrage of face monsters, crimeas, and blood crawlers. You only have 10 defense and a copper broadsword to defend yourself, and you realize that you are a ♥♥♥♥♥. If you're building a massive building or trying to get to a floating island, you see a wyvern. It kills you, or it knocks you back and you end up where you started at ground level. In a tombstone. Eye of Cthulthu will come out of nowhere, and kill you when night falls. You'll learn to love Terraria. You will.
