I'm probably like 10 hours into the new Zelda game and I gotta say I am really enjoying it. I just finished the large rift level after the first 2 dungeons.
The whole echo thing though is a bit gimmicky when it comes to combat and stuff. The game is designed around that so you aren't doing it too often and you can just bypass many enemies when walking around Hyrule. There are a lot more puzzle elements though than a "standard" Zelda game, which has a lot of them too.
My only complaint would be the framerate. It dips quite often for what seems like no reason. Like when you are just walking around Hyrule with not much going on, you will notice it dip slightly for a second. It's not game breaking by any means, just annoying.
Overall though I am really enjoying it.
