Not gonna lie it's a fun game...but: - The In-App purcharges are as in many mobile games just annoying and way too much. Sure thing if a game is fun to play i may get something in the ingame store but not like this. - The "Charts" of the Songs are quite random. Sometimes its the beat of the drums, sometimes of a keyboard or synth and sometimes at the vocals so it's less of a rythm game but more of a memorzeing game. If you are frustration resistant that may be a game for you otherwise don't DL.
