This is a nice tower defense game. I like it. Though I'm sometimes wondering if I'm doing it wrong when I start a round with only 3 towers & gems and I leak enemies even when I've already built up more towers.
I liked the Submachine series from the very first game. This one is good like all the others. Though the 7-layer thing still messes with my head to this day. Both in Submachine 8 and Submachine 9.
