Some people might not agree with me but if you're spending that much time on Titan and you can't beat it, you might as well buy a run and get it over with. If you make this amount of money in less time than your attempt to beat Titan, in a way, you're saving time which is also saving money even if you buy Titan.

Hope this helps but like I said, some people might not agree with me. I thought this was going to be another "I love the game but I'm quitting because so and so."
