It never reaches the moon. It should reach the moon when it forces the players to cash out.
Also, how does it crash it space? Maybe it blows up is a better term. You can't crash, unless some asteroid got in the way.
Great idea! I will definitely look into a way to make the rocket reach the moon when max profit is reached.
You definitely have a point with the crashing term, didn't really think about it like that, what about "Rocket exploded" or "Rocket blew up"
