I FINISHED IT! :)
I enjoyed the game a lot. It was very soothing, the audio, the smooth animations. The timeline and the rewind features were good. It was also good that you could rewind to a certain point, instead of just restarting the level.
It would have been nicer if you could toggle states of the color bars beneath the timeline with the same button (left click once - its selected, left click on it again - it gets deselected). I tried deselecting some buttons at level 6 i think, and it took me literally several minutes to realize that I should right-click to deselect the button (I almost gave up on the game at that point, but I powered through haha).
Solid game, cheers :)
