The game play is very fun even though there are other games are similar. The only reasons I rated this so low is 1: You can't run through a song once you fill your spaces with chests. SO STUPID. I don't care of I won't earn anymore chests if I keep playing but I'm not gonna pay $5 just for infinite plays. Especially since chests take a long time to unlock and gems are rare. 2: There aren't a lot of songs. Add more songs and different genres. Remove space constraints immediately.
