harder and harder + pay to win. For those who want to play this game in the long run, I recommend upgrading only the red orc. It can bring you to a very high stage. And that is a break point and leave this game or pay.

Level gate, power gate, credit card gate. This money laundering game needs to be shut down, all who read this and play, if you dislike the game, report it for Money Laundering because to top players have so much power that the only way they are willing throw the money around at that level, is if it's not their money, and they are Laundering it through this game and the devs know and probably make a cut from every dollar laundered through their game...
