Profit: is relatively straight forward, this increases the amount of money your mines/planets net you both during manual extracting and during planet cycles. ----- New Game +: Resets your progress and allows you to begin from the start with an amount of bonus dust decided by how far along you are in the game, the more mines, achievement, ect... the more bonus dust... this being said i would highly advise not starting New Game + as there is nothing really beneficial about it. ------ I hope you found this helpful, please remember to up-vote if you did so that others playing can read as well, thanks and good luck.
For anyone wondering heres some info on the buttons/values and stats.
the x1 x10 x50 is how many mines you want to place at once provided you have the money.
efficiency increases the rate of speed at with a planet cycles
selling artifacts nets you a % of your current money, so the more money you have saved the more money you get for selling artifacts, this is the fastest way to make loads of money.
After you find 3 red (legendary) artifacts, the secret planet Nibiru unlocks, which is by far the most valuable planet to manually click.
Gambling isnt worth breaking the artifacts into dust, in fact even gettign 3 diamonds only nets you a 30% increase in cash based on your current cash.
New game plus sucks lol dont do it.
hope this helps everyone!
