The is same as other idle games, with the repetetiveness and grindling or through ads simple enough to understand, free and reward players most most of the time, entertaining enough to pass time or a distraction. Art style is good. Some times the offline reward system does not work, like not registering or does not giving any.

Horrible game, there is no protection for new players so old players destroy everything you worked on for hours, and trying to make friends is impossible. So you're alone trying to have a fun but next day you wake up all that work is gone. The only way the game could be fun if you have a couple of friends so you can team up. but someone always has to be online to protect base. Other wise don't waste you're time

Extremely f2p friendly, which is the biggest draw. You can get every new character if you do the dailies. And the combat is fast, reactive and fluid. Actually challenging skill based gameplay. Highly recommended.
