Just finished a first playthrough as Hugo on Hard mode. Fun game. Good combat mechanics.
I was very thorough about getting all items and upgrades, and always cleared whatever room I was in. On Hard, I still had a few bosses where I was simply underlevled when I reached them. 50 or so deaths in without getting close is when it's time to just go back and grind a level or two.
I enjoyed this, I'll probably play something else for a bit but I expect I will come back and play through as the other two characters.
