“THIS GAME IS AMAZING. Fun, easy to learn, but not easy to get good at. When it is complete, I hope there will be an achievement for P-ranking every built-in level.”

“Although the story might just be a measly 4 levels (including Tutorial) It has really fun game play. Sure, it is hard, but in my opinion, it is still really good. There are a lot of great player made levels out you can…”

“This game is the perfect example of why steam should add a NEUTRAL rating. I love rhythm games, and love this "dodge the beat" style game. I played "Just shapes and beats" and loved it, and I love this game too. But the…”
