I played it straight after the first game and I found it pretty easy in comparison which is why I don't think I enjoyed it as much. It's still brilliant and it's obviously a more polished and even more beautiful game, but I feel like I'd have appreciated it even more if I'd waited in between the two.I've just started playing Will of the Wisps and I think I like it a bit more than the first game so far. Combat feels a little more defined, which is good. It feels a bit more like Hollow Knight, especially since they've added a similar charms system, but more platforming oriented like the first game.
They are both incredible games though and the first especially is probably in my top 10 games of the last decade, it's just that good.
