Fun engaging game leveling up is slow and grueling, crashes sometimes mid arena. The angles don't line up sometimes and my hits against opponents in the arena dont count which causes me to lose and break my streak. Everyone has the same birds and same powers so the arena seems boring. We get the same 10 birds like every update. level 161 and there is 3xthree star birds i dont have. But if collecting them all sounds like fun while competing head to head against one another then this is your game.
