There are six variants of each sound, which is really thoughtful. It's so easy to juice up a game with non-repetitive effects thanks to that.
As for the sounds themselves, there are lots of blasts, whacks, lasers and bursts, plus surprising gems like jumps, whips, coins, and twinkles. All of them sound uniform in feel and volume and go together very well.Overall, this is a pro-tier package, on par with paid SFX sets. It's really good.
