Becomes too hard
I don’t mind spending money on games like this when they are enjoyable but come on why are we still doing this? The second stage level 50 is where you need to start paying the big bucks for boosters. At least let me complete 3 or 4 hotels before spending. You might want to take a page out of other games where there is a balance of easy and hard levels and at times you don’t mind spending a few dollars for boosters. Not when it’s blatantly obvious you can’t pass without purchasing. I deleted the game
