Yeah, of course not having loading screens means we'll have puzzles like that. That makes total sense and is 100% logical.

It's becoming a little annoying how closed some fans are to the idea of change. God of War has had six games already, all sticking to the same formula. Most were great, but it was getting stale. You can always replay the games if you want that same gameplay. I mean, after all, 3 was somewhat recently remastered, right? And no offense, but I think it's really foolish to not want any character development or gameplay changes. Yes, every new game in the franchise introduced some new things, but nothing really changed. Where's the fun in that? This one is a massive change, I know. That's why it's exciting, though. If it's really not to your liking, then just let it go. As for the character, there is absolutely nothing interesting with a one-note character who just does the same thing again and again and does not develop as a character in any sort of way. That's like being such a hard headed person not willing to grow up and learn things. It's just, well, being close minded.
Personally, I think it's really exciting that Kratos won't just be killing and killing and killing. I love the idea that he has a companion now, one he cares for and will assist him in their journey. That there will be much more to the game than just hacking and slashing and the occasional puzzle and collectible. Plus, gameplay-wise, it'll be really useful to have a context-based assist tool. Players who don't want the assist and insist on doing everything themselves because that's hardcore and whatever the fuck else, well, I'm sure you don't have to press Square.
