Fun game, badly executed. Progression is slow as an f2p, after playing for a month, your power only increases by 100 when your current power is about 1.2 mil and above. Stingy with rewards! Recently, there was a bug which occurred right after an update, where people could reclaim high tier rewards over and over again. We demand the developers to at least acknowledge this issue and sort it out however way they can. But the developers are trying to sweep it under the rug.
