I got back to this game a few times and finally managed to kill the boss (the other times I did not use the abilities, so obviously I died, not using provoke is a call for death). The game is just a bit rough, nothing irremediable but the cursor not aligning with the cursor from out of the game, inventory not working perfectly, these are actually small things given the combat is actually pretty good, love me some dismembering. This is a really cool game.
