Its hard to get in the first moment but than its pretty straight forward! Nice job :D

This was fun. I've been making it a habit of commenting on submissions I find that rely on color recognition for its mechanics with suggestions about making it colorblind accessible. (I am colorblind, and I find that a lot of devs think about this basic accessibility very little). I will point out that, while the game relies on being able to recognize the color of the falling blocks, the color choices are good for avoiding issues for the common forms of colorblindness (i.e. the various forms of red-green colorblindness). I got a score of just over 70, and never felt like the color recognition was the limiting factor for me. I will say that, if this were a larger project, having the option to add symbols to the colors would be a good idea for general colorblindness accessibility.

As for the gameplay itself, I feel like this might have worked better if you had four buttons/keys that set it to a specific color each. I understand that the one-button thing was from the theme, but I don't see the added restriction as one that was used to make the game more interesting to play.

Took me a bit to realize how to change color but once I understood, it was fun and felt unique. Nice job!

found it complicated to understand because of latency for changing color but after 5 minutes, really good and appreciated !

Cool game. It's challenging, but not to hard.
I at first didn't understand you just had to click to change colors, you should probably put that in the description.

Fun game to pass the time, could work very well on smartphones

The scrolling mechanic gives a not so easy game, challenging, nice work!

I confused the color guide on the very bottom for the bar and spent a few attempts trying to change it; you should probably move that to the side or something. The game was pretty fun once I got into it, the timings felt good, but it could really use some better explanation to reduce friction.

really neat concept for a rhythm game! i wish the color of the bottom bar changed instantly instead of smoothly fading; quick feedback is important for rhythm games. could be a good mechanic for a more developed rhythm game where the gameplay is more synced with the music!

I can't seem to survive more than 2 seconds lol. Would greatly benefit from some sort of controls explanation
