Interesting and super polished, but the super random nature of what's next kinda makes it feel pretty arbitrary, and the lack of "comboy" mechanics hurts it somewhat. (Yes you can intentionally stack up a bigger chain to pop all at once but that doesn't feel clever, it feels more like you got the right piece before you got choked out more than you feel like you made a smart play).
Kinda wonder if the rules could be iterated a bit more. I think there's potential in changing the needing to choose one of x number of connections sometimes thing, that feels clunky and less interesting.
