I been playing the game for a while now , and at some point you gonna full upgrade all the equipments and you gonna upgrade your cloths , after level 70 when you do the 18m upgrade , its gonna ask you 0 coin to go to the next level , don't do it or you gonna lose money instead of winning , this bug should be fixed asap. Bit overall this game is so good and i highly recommand the cat to skip videos .
