By timed he means that he cant play forever without interruption because of stamina and no the game does not "steal your money" credits are earned by daily spins too.
Time dilation only happens when something moves very fast......So.....Why can't the base simply move somewhere else when your entire facilities are in danger of utter annihilation?
Tip: (might be wrong) In gold leaves mode, if you don't win fast enough, you won't. Instead of dragging on the level, just restart the level you are doing or try another one for xp. Rate up if this is right rate down if it's wrong.
