The demo for the visual novel rhythm game Clash of Melodies.

It's telling the story of two dorks who don't like each other going on an adventure together.

This game features two rhythm game modes: One DDR / FNF inspired "Arrow" Mode, and an original "Circle" Mode, in which you have to catch the incoming note with a circle in the middle. 

Beyond that, the story is told through classic visual novel style text cutscenes, as well as a few fully animated sequences. 

Once you have beaten a stage in the story, you can go for a highscore and a full combo in Freeplay. There you can also choose a hard mode that keeps a separate score.
