If you enjoyed the first game at all I highly recommend Will of the Wisps, it's better it basically every way.
I loved the first game. Everything about it, really. So if this better than that, I'm in for a treat. I'll give you my impressions after digging into it four a few hours.
There are some people who don't like it as much as the first one but I'm with Curl in that I find it better in every way and I think most people feel that way too. And yeah Blind Forest was great already, Will of the Wisps is just amazing.
And yeah the autosave system is very lenient. It works on a checkpoint basis, actually it kinda works exactly like the saves in the first game, but instead of you having to manually make the saves, they're just invisible checkpoints littered everywhere. Obviously you still only get saves in stable ground, so water levels and certain platforming sections will require a bit more patience. And of course you still don't get autosaves in the escape sequences.
