Okay, the two endings are way too similar. I can't see why one is 'good' and the other is 'bad'. One gives a creepy detail of his youth and the other rails on you for blindly following directions, but the end result is the same, confusion and random uncontrolled self-cloning.
Okay, come on, do you really have to make SO MANY CHALLENGE LEVELS!? I'm pretty sure if I can make a 30m bridge I can also make a 31m bridge. Make the distance go up faster, come on.
