Lovely game, very chill. Great idea with using color mixing and cable weaving.
The balls move very slow, they could be a bit faster imo. If you did it because of physics stability, I can understand, but there are a lot of resources online for 2D cable/rope bending.
And it would be nice if at the start of the first level, there was some UI overlay pointing to theball saying "Drag me" or something
The animations for level start and end are lovely. Nice game
