I definitely enjoy a challenge but the newest update has increased the difficulty of the game WAY TOO MUCH! I have spent a couple of years playing now and have put money into the game as well, getting my attack to 20k. The recent update increased the hp and attack of enemies in the game to the point where I dont even want to play. I love the game but adjust the difficulty because the enemies are way too strong now and it is honestly making the game feel like a cash grab. Horrible decision...
