I spent way too long trying to get this score..

I love how clean and simple it is, yet there is so much to it and a lot of detail. There seemed to be multiple ways to complete the goal at times, which is bonus points for me :) The only thing I was hoping I could do was right-click to remove a color. Other than that, I find nothing to critique, it was great!
This was amazing. These are the types of games I build and love, and it was done so well here. Great level progression and teaching the player the mechanics. Awesome job at introducing new obstacles, there's so much content! I could play this game for hours.
I can see unlocking the ability to swap midair, as it could add some cool timing puzzles. Really good job overall!!
