Just Pay to Win a game

At first, it will be impossible for you to win a hard enemy unless you upgrade. Then after that you will win as if you were kiling a mosquito.
You will face harder enemies and have to upgrade at every level.
After a certain stage, it is not possible to upgrade unless you pay. Even if you fight well, and system doesnt want you to win. The enemny will take out your entire life in just a single blow,
Dont waste your time in this game if you dont want to pay..
