Trapped!

You decide to cut off your right leg. You grimace and scream in pain as the machete goes through your flesh, muscle, and bone. You cry out when no key falls out. Then you see something inside your bone. Something shiny. You take it out and look at it. The key! You begin crawling towards the door when you hear an alarm sound, and a timer appears on every screen. 0:30, it reads. You crawl as fast as you can. 0:15, it says. You finally make it and put the key in the lock. 0:05, it reads. You turn the key and push open the door. You push yourself through and turn around. At that moment, the timer reached zero, and spikes shot through the floor. You sigh in relief. That's when you hear the familiar voice. "Good show!" he says. "Are you ready for round 2?"
