YOOO THIS IS SO COOL, It's like Cooking Mama x Rhythm Game, Love it! The cooking sequences looked beautiful btw, props to that! The music is very catchy with the game too. Probably a suggestion is to give a particle effect when you hit the notes with the line, I think Unity has an in-built particle, and maybe add a knife slash sfx like fruit ninja whenever u manage to hit the note (just a thought xd). Like Taiko Game kinda stuff, but overall love it! The idea's great too :)
Excellent game!
