Bank Error in your favor. Collect 4.6 quattuordecillion dollars. (had only earned 500 tredecillion all time, a glitch gave me 9x that after being offline for 30 minutes)
took 75 minutes, was level 12 when I won. Start by prioritizing batties, bat gang, and blobert. Once you get a high end kicker you'll mostly be over water so blobert is irrelevant, so get batties and bat gang to level 7, I put the rest in "Make it Bounce" although the next gliding passive would be much better, just didn't unlock it before I won.
If the offline bug is indeed caused by the calculation taking too long, then it could be avoided by having less money earned while offline, or perhaps by having a faster cpu. I am basing this on seeing a significant delay before my money is added in when I go online, and only having problems at larger amounts of money.
I have a guess that offline mode not working is related to high levels of income. Early during my last restart, my offline mode worked 100%. Once I get to the point where I have 2+ tredecillion I should get when I login, there's either a pause before I get the money (for the lower amounts), or I don't get it at all. Maybe the calculation is taking longer and times out. I haven't coded with such large numbers, maybe a buffer time is needed on startup to let the game compute and add the money?
Want to know how many times your Lemonade is triggering per second? Base is 2 per second, so for each speed boost upgrade, multiply by 2. There are 17 speed upgrades, so the highest possible speed is 2 * 2^17, (2 ^18) lemonade triggers per second, or about 131,000.
(edit)*Some "Real world" breakdown for Lemo vs Oil Well, with 1000 lemonade stands, 700 Oil Wells, and 525 newspaper, Lemonade purchases should cost 20x Oil Well. With 1000 Lemo, 600 Oil, newspaper >= 375 and <525, Lemo purchases should be at x6.67 the cost of Oil Wells.

Late game you should invest into Lemonade Stands where the next costs many times more than the next Oil Well, about 572 times more with all achievements. i.e. 100 nonillion for next oil, 57,200 for next Lemonade. Base efficiency w/o multipliers puts oil wells at 129,600 greater than Lemonade Stands. However then Lemonade stand offsets by 3 * 4 * 5 .. * 8 for Newspaper achievements, and 6 lemonade upgrades of * 7 compared to 5 Oil Well upgrades of * 2. Think my math is right.
I think once you get to super expensive assets (like 250+ octillion for oil well, this is at 600+) it's better to restart daily as those angel investors increase your income more than the few assets you can afford. Starting to track my AI earned per day, and so far it is 1.92 billion day 1, 1.98b day 2, despite them getting more expensive.
"Could we have some more decimal points for Angel Investors."
I agree with this comment, however instead of decimaled billions, perhaps just millions could be used (1 billion = 1000 million, etc.). I like the non-decimal look, and long before you get close to a trillion, you've already got 500+ in each upgrade.
With 15 billion angel investors and 10 nonillion earned (low compared to many, I assume), I have no problem with a complete reset of scores. Starting from fresh is fun.
It seems that you get just about even value from a business upgrade being 4x more costly than the upgrade for the next business down, assuming that they are at the same speed. i.e. if your next Oil upgrade is 600 trillion, then you should upgrade banking up to 150 trillion cost.
If banking had a speed boost over oil, then it's a 1:2 ratio, 300 trillion banking, 600 trillion oil.
My process after restarting with more angels: Sequentially get everything up to movie theatres to 50-60 (depends on how many angels, lemonade goes to 100 though). Put 1 into banks and oil, the time bonuses with achievements applies retroactively (make sure you don't accidentally finish them before you upgrade). Before putting any more into them than 1 in them, save up for the monopoly upgrade. After monopoly, you can put the businesses all up to 60-65 (+20-30 for lemo) while you wait for the funds to get banks to 50. After B50 gives you an influx of money, get oil to 25 for the universal speed boost. Then save up for oil 50, ideally you will get closer to 70, before you get your first income from oil! Now your empire is up and running.
Coin bonuses are OP. In a launching game, income from the launch should be larger than from pickups. You can easily have coin pickups generate 4-6 times more than your launch stats.
