Basically what I assumed, some great exploration hampered by some shit puzzles, wonky over complicated controls and huge seemingly random difficulty spikes. Holding out for some fixes and updates
But you know your e-peen will be impacted by this right? When you finally get around to it and you comment here that you played it, had some difficulty with some bosses, but with doing X, Y, Z you managed them, you'll be met not by praise for completing a challenging encounter with smart skill use, but with "Pfft, did that pre-nerf where HP pool was bigger, skill X, Y was bugged and Z feature didn't even work!!"
Joking aside, the difficulty mentions in the reviews makes me want it more, not less. One worry I had was that it was huge and rewarded exploration (that was mentioned in previews), but I worried that like most open world games it would become a "press X to win" in later stages. If they have not just one difficulty spike like Elden Ring (Winter area), but several. That's great.
However, if the difficulty spikes are just tied to larger HP enemies with a combination of bad controls which makes effective skill use impossible at the same time as you struggle with camera/lock on, that's not good. But from the reviews, while that is an issue, it doesn't seem like it is the only thing that makes it hard.
What nearly all the reviews mention is that it is very focused on exploration, and actually rewards it. That puts it very close to "take my money" from me.
