Time Quest

I'm doing this for the Time Quest and to try out some screw-loosening type games, but the Time Quest rewards are different every time. If it was a lot at first and then decreased, I've seen that in other games, but it's different every time and even increased. It was 1600, then 4400 the next time, and around 2000 after that. It was the first time it increased, even if temporarily.
