Prey For The Gods PS5 - Final Boss already? - Hard Difficulty

I love Shadow of the Colossus. This is very good, but if this is the final giant, it&a bit dissapointing in length. Also, I have only found 1 piece of armor so far and I am still wondering why I even need armor. Seems like a not thought too well about type of problem. Seems very easy to speedrun this even on hardest difficulty.
