After hitting AI's in duodecillions there's nothing much to do, just let the game be and visit from time to time to reset. I don't actually see how can this game be upgraded more, but that's what the devs are for, I'm sure they'll do something that'll make me go crazy again.
It would be nice if the stands increased a bit more when You get all the achievements, like let's say 25% every 100 bought after all achievements were obtained, this way buying more than 900 oil stands will make sense.
Offline mode works fine for me for days now, I don't know what causes the bug where it doesn't work for You guys but it shouldn't be the game, I'm back at 15 quad AI's so it's not about high numbers, maybe Your browser?
If the offline mode doesn't seem to work make sure You're logged on kongregate and try using firefox, it works fine for me and I'm always logged using firefox. It did NOT work for me while I was using chrome.
@askdaxbox, yes, they're now permanent, at late game it literally makes no difference since You get more and more AI's. In about 8 hours today I've made from 1,xm to 1,5quadrillions AI's.
I would like to endlessly thank the developers for this game, especially this new update that will keep me playing for the next 50 or so years, thanks You honestly, one of the best flash games I've ever played in my life.
Good earth combo, get 5 earth points and summon earth hermi, use narute ritual to heal Your hermit and Rejuvenation to heal Yourself, after gathering enought Earth energy summon another one (earth now increases by 5 each turn), summon trolls and use rejuvenation whenever you want to. Troll heal 4 HP each turn, Rejuvenation heals 2x the earth power, earth hermit is 1/13, naruto ritual heals 8hp to chosen creature and 8hp to Yourself.
