Is it fun? No

I was blown away by the first half hour, the setting, graphics, sound, the lore...wow, just great. Not much combat? That's fine. But the puzzles, which are almost all you do, are not fun, unintuitive, involve back-tracking in a forest, and do not give feedback to progress. For example, I got a shape off a locked door to match in the environment, otherwise I can't open the door, just like a prior puzzle taught me. Can't do it. Eventually I give up and reference Youtube. Silly me, I was supposed to try to open the locked door, which I KNOW I can't open yet, to have a cliff wall disappear, which is where I have to go. What? I have to do something the game taught me wouldn't work to magically have a way to progress? Then later I couldn't tell what was a portal for awhile...ugh. Watched more of it on Youtube, the game just gets even more boring and tedious. Did reviewers play this more than an hour? This is possibly the most over-rated game I've ever played. I'm just shocked.
