Level 115 is the first real wall you come against so far. With all upgrades purchased and the only way to further increase your DPS by any noticeable means being through the use of Energize and The Dark Ritual, it's going to take forever to become strong enough to beat it. At 10,000Q DPS I can't even take off 1% of his hp in the 30 seconds.
I have 16 billion AI and make roughly $2nonillion cash every 24 hours. Considering that just the 500th newspaper stand by ITSELF costs $133nonillion this is going to take many many months to achieve. I can increase my AI by about 1 billion more every day or so, but even so, it's a long way to go. Long. Very long. So to all those just starting, you have your work cut out for you.
This game is a Monster Rancher clone in almost every single way, with less variety and content, and way too many bugs. Also, no challenge whatsoever. You start off winning, and only progress from there.
That path is about to become a LOT shorter! More profits (but, you know, still keep the game balanced and fun!)
