Balancing really needs to be looked at. It didn't take long for me to get to a point where I had to start using an autoclicker set to a click every 1 millisecond to get anywhere. Took just over a minute to reach 1 million (If I was manually clicking, it would have taken roughly 15 minutes to reach 1 million?). At lvl 19 it costs over 1 mill to level coffee break. Even then that will only be a slight increase. As it stands it would take 16 hrs to reach 1 billion if I bought no more upgrades. With the way upgrades are going... maybe I could reach a billion in (optimisticly) 8 hours? There isn't enough going on in the game to be worth investing that much time.
Things would be more doable if every 10 levels the increases went up by 1 and every 25 it doubles. So at lvl 10 coffee break goes from +1 to +2. lvl 20 is +2 to +3, 25 is +3 to +6 30 is +7, 40 is +8, and 50 would be +8 to +16. Then the same kind of thing be done for the other upgrades. Even then it would probably still take a couple of hours to reach 1 billion. Price increase should be reduced.
