Pretty nice game idea. There seems to be a bug sometimes after you lose 1 out of 2 or 3 balls - you can keep playing but no squares appear (see the screenshot), had to reload the page. Didn’t understand why do I sometimes start with one ball, sometimes with two glued balls, sometimes with two balls that behave independently but collide inelastically, sometimes with three balls that go out of bounds of that line for balls, etc. I’d say the mechanics need some explanation. Anyways, good job!
