Wow. First time I was lost, took a day's break only to come back to the game and really appreciate it. Once I got the hang of it, it was really fun! Granted I only got through to the second level, I can imagine there is even more to the game than I found out about. Well done thinking this up man!

I don't know if it was only on my hand but the speed of the cristal was too fast to be somewhat controlable without shouting.

On the other hand mechanics are super interesting but could be introduce a little bit better in 3 phases :

- first few level focus on subtracting color from ennemies (the right color, then a combinaison) with a timer that reset the ennemie to negate mistake

- then the new few focus only on adding color on the same principle a above with the addition of the changing cristal color mechanic

- and finally a combination of all of the above 

Great game with great UI. The only issue though is that it is hard to tell what color the enemies are sometimes.
It would be nice if there were sliders saying what percent color enemies were.
 Also, give the background some light so I can see dark enemies.
 Thank you.

The audio broke up a little on my Windows 10 gaming laptop. I could hear crackling, like the sound wasn't playing right.
