Cute runner! I included it in my compilation video series of the Ludum dare 42 compilation video series, if you’d like to take a look :)

Hey! I just wanted to let you know that a video of one of my playthrough/reviews is up and you're a part of it!
Take a look here:

Welp, that was a thing.  The music was a bit interesting.  Very conceptual, contemporary =D  The blue notes slowed you down, the pink went faster.  That was cool, except I collected two blue notes and the game just stopped.  Wah wah... Interesting concept, could use a bit more polish =D 

Great work!

Didn't get why Red and Black were supposed to be avoided! Maybe if they were 'Rest' music notations instead, that would signify that the game would stop, it would be better.Also, catching Blue really slows up the gameplay and I always avoided it. 

There is no objective to the game other than see how far you can go! Maybe a points system would be really nice. I liked the game, it's a fun little game. :) Good job!

Being able to change the speed of an endless runner through objects is a cool idea. 

At first I thought the red note was just another note to increase speed. I'd probably make the red notes easier to differentiate from pink notes.

The concept itself is great, it let the player ajust his own speed (I taken all the red one for some speed bonus).

Need some work but there's something ! 

I like the idea of the game, in that it's a platformer where picking up different notes changes the music/speed. But like what n00begon said, getting two blue notes in a row (and not knowing what would happen) just instantly ends the game. Similarly, there are often times where you can't get away from hitting a red/black note even if you don't want to. Needs some work but has a good idea!

I like the notes changing the speed of the game and the music. If I get two blue ones in a row at the start I slow to a stop, I assume that is not the intent.
