Really nice and minimal concept (and UI). I like the juicyness!

Levels get pretty tricky quickly. Got to use some spatial thinking to solve these. Nice puzzle, Roxor !

Rock on ! 🎸

Fun! I got stuck at Neutron Star. It would be nice if there was an undo button.

nice UI. wish there was an undo button as well.

Umm ... ? Guys, there is an undo. Click the same area again and it will return back. Remember this is an XOR puzzle.

Choose CTRL-R to choose and start the same level again.
