I really liked the rhythm game idea, but I did have some issues with it:

1) It really could've used a tutorial, I was really lost for most of it.

2) The gameplay didn't feel very fluid. Like I get that the things were moving on the beat, but there was probably a better way to implement it, like for example have them speed up on the beat instead of being completely stopped. I'm not totally sure I just know it felt kinda weird.

Other than that, really cool concept, and I thought it was fun to play.

Good interpretation of the themes and challenges, you were able to check a lot of the boxes. Enjoyed the music and the premise of the gameplay. I ended up generally sticking to one corner unless there were  a lot of obstacles ahead, which allowed me to walk past a decent amount of the obstacles with not much effort. Maybe forcing the player into the center during checkpoints would force the player to interact with the obstacles more. 

Interesting idea, and sound implementation. I tried quite a few times to make it to the end but in the end couldn't - but I think this is something a balancing pass would make into a really fun game. A few points:

• I could see the triangles were somehow flashing with the beat, but I could never quite tell where they were or what sounds they were reacting to. Perhaps these could be better telegraphed in some way.

• At one point I got stuck at a checkpoint for quite a long time as blue squares had stopped in a complete line in front of me and the checkpoint I was on was a stop movement.  As I couldn't move left or right, I was just stuck.

Good job hitting all the diversifiers though and I think it really fits the themes/limitations. I think you do have something good here overall.
