I've beaten the damnn thing like 5 times now, how many times do I need to kill the fucking dog? Such a stupid part of the game because u get no feedback, and the big door is still not unlocked.

The worst part is that this part of the game is a giant bore fest

it's a dream sequence, there are 2 levels that tou only need to clear once for the main story. There should be a star on your map Fae pointing a portal in your book
