Finished my 1st playthrough
I absolutely loved the game, i picked the saw cleaver when i got the badge and decided to finish the whole game with it, same for the 1st pistol.
About some bosses:
Design wise, my favorites were mergo's wet nurse and ebrietas, specially ebrietas.
Fighting wise, my favorites were mergo's wet nurse and gherman; my least favorites were the moon presence (it wasn't hard, just the first few times i died i hated how strange its range was and how random some attacks could be) and micolash (mostly because of the running, which i thought was a funny gimmick the first time but it started to become annoying); the one i struggled the most was ebrietas and the ones that were easy were the amygdala (killed on the 1st try) and gherman (since its pretty easy to parry him)
As for the zones, forbidden woods was both my favorite and least favorite to explore.
Ps: i shouldn't have trusted the cannibal npc and i only realized how to use the runes after killing the wet nurse lol
