New update

All good now

They took my money !!!!!!!

Ipayed two time For mounthy vip and its not work they took 20 usd and they didnot give me the subscription and there is no one you can contact or support
Itryed to send email and no one respond

Fun, too many Ads

Love the range of character and combinations to use, but it requires far too many ads and progresses too slowly. Easily 30 ads per day to get daily bonuses and only play 5 rounds. This is an ad engine disguised as a game.

New update is trash

Been playing this game for a few months. The resent update made everything weaker it seems. Mobs have way more hp or Im not hitting for much damage anymore. Was hitting with my death ray for almost 2k now i hit mobs for less than 100 half the time. All daily rewards and ad rewards were lowered in value or cut in half. Were it may have taken a week of grinding to advance through the game levels now takes twice as long. Ill be putting this game down until they can balance out this new update better. Disappointing to regress due to a poor update.
