Most jam games are super hard and/or difficult to understand =)

This one has a basic and efficient gameplay, and starts easy, so it's really a nice beginning! Though, like Narkhos said earlier, it would be cool to spice things up after a while. Having things go faster each minute or whatever could give an end to each game with a relevant score (otherwise the player will just quit if it seems to easy and endless).

Good job! Hope you'll update it a bit :)

Nice rythm game! I definitely need more challenging patterns. Maybe you could add a difficulty mode where the green line just follow the red line (with different distances according to difficulty) so it could be more dynamic. You can even add some "holding button" pattern to simulate a bend or a slide. Great concept and you even have a tutorial mode. Keep the good work!
