今日は私が不運ですね?

Essentially, one mundane day, on your way to your mundane job, somehow, your car exploded. As you fumbled around your now-flaming Toyota Corolla®’s multiple gadget holes for your mundane cellphone, you were transported through quantum time fluctuations generated by your exploding mundane car to what appears to be a gigantic tower! Not particularly worried, you slowly dial your mother to tell her that you'll be late for dinner. Unfortunately, before you could finish pressing so much as 1-2-3, you hear a groaning sound above you, which you discover to be a gigantic spiked disk of incredibly lethality. Even more unfortunately, you discover that the groaning noise was the result of faulty screws and supports allowing the gargantuan plate of doom to begin a slow descent towards the ground, and predictably, you as well. Sighing, you begin to jump down towards lower pieces of ground in this infinitely deep tower, avoiding other, smaller pieces of pointy spikes as you go.
This just isn't your day.
