So far I think it is a fair challenge, there have definitely been some bosses that initially can feel cheap, but like you say if you observe what they are doing then they are not too hard. Also you do have to pay attention to what the game is telling you and giving you, if you don't parry and harvest rot powers to hit the plants and power up mid-battle it may seem more challenging.Lol people really dont like challenging games huh? I wouldnt even say kena is all that challenging, i think people are being over dramatic about the difficulty or dont know how to observe boss loops properly.
I'll caveat all of the above with the fact that I've not finished it yet, think I'm about 6 hours in with 26 Rot and one weapon to still unlock.
