This looks intriguing! Unfortunately, I wasn't able to find anybody to play with when I was checking this out, but assuming that I've understood the concepts, freeform "draw with particles" as a shared experience where players vote on whether they're ready to move on or not feels very nice and relaxing.
The visuals were nice, though I do find I have a little bit of trouble differentiating between the green and pink fragments with my form of red-green colour blindness.
Hope you had a positive experience using Godot, and thanks for doing a Linux build :D
