I tried to find a recommendation no one had sent, but looks like people covered it all, even the sugestion to use forms along with the color to increase the acessibility, so all I have left is maybe you should add some screenshake to improve the game feel. Anyway, congratulation for this is a fun and nice game!

Very addictive game. I really like the particles when you died. Although I think the player could be a bit more snappy. 

It's cool game but too simple, screenshot show things i didn't see in game like characters and settings

you can make the game better if you add:

 more levels-stages

characters

 mods(touch same player color, avoid same player color, reach specific score to win)

you can add abilities like big bang you press button all things destroy 

hiding ability you hide for amount of seconds

and you unlock these abilities when reaching some score idk 

good game after all

Really fun game. You set up the death screen really well to cause people to have to play again. I think that the purple and pink colors are too alike and can be hard to differentiate. It is a very well designed game!

Nice and simple arcade game, the graphics aren't too detailed but I don't mind that. The character controls do feel really slippery, so it makes it easy to run into enemies while trying to get a square of your color. I didn't find myself using the second rewind mechanic too much (rewinding time), I think having short bursts of enemies where the player is either forced to rewind and then position themselves, or if they're close enough, just position themselves would really help make use of that mechanic. Nice work!

Good game.  The need to play one more time is real!

fun arcade game!

Super fun arcade game!! Did not understand how the theme was implemented until I finished playing and read it here. A small tutorial or a How to Play would have been nice.

But it was awesome!!

Very smooth and unique game. My only complaint is that you've seem to have Vector3.lerped the movement of the ball which removes a lot of precision. Otherwise, Great job

This game def has that, one more time, feeling. Every time I was thinking I was done playing, I'm like ok just one more :p  nice job. Feedback would be on the controls of the circle. Not sure I like it slowing down, would rather it stop the instant I lift on the key, I think. 

Niceeee i loved this game!!

This game becomes a bit of a puzzle! 

Have you considered making the time-bar the color of the next color the player will be instead of the current? This could lead to the player making some interesting decisions to put themselves in a better position for the color change.

Nice game overall. Seems like it would be a great mobile game. The controls weren't as snappy as I wanted them to be which made it difficult to pass some of the more difficult waves. The rewind mechanic worked well and I think it is a nice touch. With some fine tuning and better graphics, this would be a great game.

Good fun! Having to flick your eyes from top to bottom constantly  to make sure I knew what was about to happen really kept my heart pounding :D

Cool concept! I would totally play this if it were on mobile and if it would be a bit more polished. I do think the graphics could've been better, but they are not bad. Good work!

This is a good game! I think the take on the theme is pretty good too. I just have one tiny remark: A and D keys are working but not the W. Either make them all work or remove the A and D keys. I also encountered that in another game so maybe it's some predefined settings from Unity or something...

Anyway, good work!

Edit: Also you could improve the game by giving a color-blind options (I don't expect that from a Jam game but it could be a fine addition) and using forms instead of colors.

I played 10 rounds just to really grasp the game! While not being the type of game I play (so I'm not the core audience of said games) it was still enjoyable! I tried to connect what I saw to the "rewind" theme but couldn't connect the two, I did enjoy the color patterns and the audio however! Was enjoyable!

I would like to play this one with mouse (or touch in mobile devices) instead of keyboard, that way I could move more accurate.

I always confused pink with purple, but that's my problem :)

Graphics and audio are great, simple but very effective.

Colors are changing so fast, which is making the game hard, but the difficulty is not insane. We always like some challenge, huh?

This game is greatly enjoyable to play.

This is a simple and enjoyable game. As others have said, this type of game is perfect for mobile phones. Great job.
