Stambled on couple of bugs on my playthrough. Music from main menu was looping all the time and no impact/enemies/environment sound's were there... On the first boss you can just stay in him and he couldn't damage me, besides his one shot attack, and trigger for 2 ghouls before him can be bypassed on the side in the bushes. On the second boss i just randomly pressed attack before the green gates and locked on the boss, leaping on the arena, it resulted in AI freeze of the boss so he was just standing there, when i was slashing him...
But third boss was really cool, and design of the MC are great, love the IDLE pose!
