Wonderfully tight and polished metroidvania with a wide variety of abililties and weapons. Can't emphasise enough how good to play this one feels - it's snappy and perfectly tuned. The souls system introduced here is brilliant, both allowing for a lot of cool abilities that get you into new areas, as well as a ton of optional ones that are just for fun. This was the first of the series, or even the genre, that I played and it's still one of the best.
