I have been playing this for quite some time now, and have levelled up plenty. The coin collect sections to actually play are very low compared to the level I am at - meaning that it can be near impossible to complete challenges and requests. The coin collect will be about 1B, but I need about 30B to play features However, if you want to fully engage with everything you probably have to spend money. Problem is once you make a purchase, they put the price up if you want to make another purchase.
