BODY SIZE, said the screen. Underneath, three options were listed.
adam62281's suggestion: double
Sphinx_Yawn's suggestion: +6" height
Bbhhx's suggestion: gain 50 pounds
At the bottom of the screen there were some rules, which Kieran glanced at but didn't care to read. The whole app was a waste of time anyway. He chose Sphinx's suggestion, just in case something interesting would happen in the game. "Your choice will soon be applied," another popup said. "You will be notified when another turn starts. Enjoy!"
Then Kieran felt something crack in his spine as his body started to grow.
The process wasn't painful, but it felt very odd and uncomfortable, and also Kieran was panicking the whole time, unable to move for the whole five or so minutes it took for him to grow six inches. Suddenly a lot of the weird text in the app made sense: it changed the players physically, through some means Kieran did not even begin to understand. His mind raced with chaotic thoughts as he lay on his bed listening to his bones lengthening and his flesh being reshaped.
After it was over, and after another couple of minutes he needed to calm down, Kieran got up. He used to be an average 5'9". Now he'd have to watch out not to bump his head on the doorframe. Somehow, his clothes still fit him, evidently also having been resized by the app. And it looked like he hadn't been simply stretched out — looking down at his body, he saw roughly the same proportions as before, with the same average body type and the same skinny limbs. He wiggled his toes. His feet were a bit larger now, suiting his new height.
Still confused, Kieran didn't react to the sound of the door opening until he was standing face to face with his roommate.
