Listen developers, you are the most greedy persons I have ever saw in my entire journey of gaming. I made small purchase in the game and this was my first in app purchase of the game and since then the game has become terribly difficult. After purchase, for next 3 levels, I had to spend more than 80 lives. Definitely the game is making the game harder after purchase so that I buy more golden currency. Literally the time I took to reach level 711 from 381 is same as the time I took to reach 715 from 711. Listen you fools, I won't spend a single penny on this game anymore, do whatever you want and make as hard as possible.
Shame on you. Greedy demons. Useless creatures. (I don't want to abuse on public platform but you guys deserve it).
