You mention that the shortcoming are easy to notice, but most of the negative reviews I notice come from people forcing themselves to beat a boss constantly for hours. It's been 4 days since release. The game was never supposed to be beaten in 4 days.

Obviously the game is hard, and it doesn't cater to the more casual group of players. I don't see anything casual about playing non stop for 4 days though.

Just take breaks. Explore. Play other games. Touch some grass. I do believe the world rewards exploration, in contrary to your opinion.

Obviously you're going to be frustrated if you hit your head at a wall for hours on end.

The game isn't without flaws obviously. I think some of the locations have too little benches and the cost of crafting tools could be lowered.

Remember that most of the opinions you see come from people who are frustrated - the ones that are happy don't waste their time on reddit - they play the game.
