“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.”
“10/10 The editor (which is most of the game's content right now) can be hard to learn at first but is super fun to use once you are familiar with it. There are a vast amount of player-made levels on the workshop, most…”
“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…”

“The story is Incredibly short currently, however it's a really promising project. I could definitely see this taking over Just Shape and Beat's legacy once it's fully released. The levels themselves are a lot more…”

“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…”

“While the name change may be controversial, the original was long winded and hard to read/spell. I personally like the new name, maybe keep the old name as a subtitle. Yes its essentially JSAB with custom levels, but…”
“The game is very fun, but is buggy and certain mechanics need work. Other than that, great game!”

“Pretty gud. Only criticism I have is sometimes the visual effects can be a bit much, and all the different colors and warnings can get way more confusing than JSAB. Oh yeah, the name change is weird also but not a huge…”
“i love this game but you have to find custom levels by yourself”
