Changing review to 1 star.Mytona made it impossible to play without buying rubbies. When I reached 6000 stars,restaurants became extra difficult.Although I upgrade to max many of crucial items,I am not able to pass a level until buying a booster or paying 20 rbs - for which rbs are needed. Honestly I should stop playing since it's not enjoyable anymore.Please don't say that episodes,guild quests and events will bring rbs when passing levels is needed for that, but user is stuck without booster.
