Fantastica is a gacha-styled TD, though from what I remember from a few years ago when I last played, it's not exactly...strategic. But I also didn't get beyond the first couple of hours. I don't know if there are any cool 'towers' like "freezes enemies" or "does massive damage but has low firing rate" or anything though.
