If you want to build up money, don't manually power up the booster things. Once I stopped manually powering those up I started gaining money, instead of it dropping. Assuming you have changed the sell sliders.
A button allowing to buy multiple upgrades at once would be nice.. like buy 1000 passive xp boosts at once by only clicking once, because you get to a certain point where you have so many SP like I have 1900000000000000 SP and it takes FOOOOOREVERRRR to buy loads of upgrades.
Pleaseeee xD
