Well, yes, you should have been. I wouldn't have developed an acute hatred of merkids for another ten minutes.
You'll love Mothbees, then.
And Yellow Slimes.
And Kobolds.
Oh man these enemies.
Oh, that's easy. You know what sucks? Two merkid leaders and one merkid mage. Or Poison Mothbees when you forgot to bring antidotes. Or a five-enemy clusterfuck of Sabercats Poison Mothbees and palette swapped Myconids. Or being under time pressure in solving a rather tricky riddle because you are poisoned and Sana's nearly OOM and you ran out of Better Herbs and Antidotes several corners ago. I arrived at Chantreux like two venom hits before death with Sana down. That's the kind of gaming moment that sticks in your mind.
Kobolds would be pretty easy if they didn't have guard-breaking downstab. Can't really get their guard patterns down, only kicking them in the face seems to work consistently. Yellow slimes don't guard but their range can be annoying. And Orgs don't give a flying fuck about whether you guard or not.
I wish the bosses were as hard as the rest of the game is.
