I got to give this game a second playthough to properly explore the game's mechanics. I guess so far, it be nice to have a visiual indicator my pets are connecting.
As for limitation, there are more then 3 collors technically. If you count black and whatnot. but I like the art style! And acording to some QNAs i seen, the limitation is vuege. I love the art style and concept!
I may give a follow up comment later!
