I didn't know what I expect, and I saw that it's a rhythm game. I played with it, and I vibe with it like any other rhythm game.
Though, the game did lack some UIs including bars, but most importantly, it would have been great if there are sound effects when you press the buttons. In most other rhythm games, there's SFX for perfect, bad, and miss inputs.
As far as I can tell, the music had similar bpm to the rhythm inputs, so I didn't feel disconnected.
