4 stars: Every song is easy, the expert difficulty is easy its not even difficult. No challenge to these songs Update 8/14/22: Everything is the same, they added challenge mode, it's still easy. This difficultly setting is weak.
3 stars: It's a decent time-waster & has good graphics but it has some issues. If you hit a wrong bar & revive, the song is off-beat. Even the hardest songs are super easy to do well. And the songs are either clips or are copyright-free versions (including remixes, instrumentals, etc.). This game is pretty good for an ad farm, better than a few I've seen.
3 stars: So this game is pretty good, but it's not really optimised for Chromebooks. Whenever I unlock a new item, a black rectangle covers a third of the screen and I can't make it go away. I also am locked on that screen with ads occasionally playing as I try and get off of the screen, but the only way to get off it is to close the game and relaunch it.
2 stars: I love the concept.. but the songs are super short and there's not many only like 30 or so you can play. My BIGGEST problem though is that stupid sound effect when you hit the notes.... It sounds like someone slapping wood. It completely ruins the experience. Cool graphics. But.. I just can't with the sound effects of the note hitting. It ruins it for me. I wish you could just turn it off or they would change it. PLEASE change it.
