Warning: In the Cherry is Cumming update... After finishing the 20 levels of the first room you then get an offer to unlock "Furnish" the next room. This has a 24 hour waiting period that you can skip with 15 diamonds. After unlocking that room, if you reset again to get more speed you lose the room. :/

I am now guessing I will hoard up into the nonillions then see how far i can unlock with that cash.
