Great game but annoying

In my opinion
Great fun game at first !!
Im level 7-8 now and was addicted and kept playing but it seems that the only way to keep having fun and to win more or level up you have to spend money to armor up or have extra to help you
It is too bad they dont give you bonuses or extras/achievements as you play so that it doesnt go straight to paying for stuff for people like me I dont have much spending money! So Ill probably be deleting it soon
Thats just my opinion
Later! ! !
