The map is a definite improvement over the previous, and i'm envious of your ability to dish out so many brushes so fast as i tend to overthink each brush. It has a lot more personality and variations in each room but it could go with a bit more on that yet. The layout improved also more except maybe in one part where there was two ways, one for the Gold Key and the other ended out of nowhere on a room with two doors, which i suppose will open from the other side to connect the map later. The inclusion of the water parts is well done there and fitted the map well. The gameplay seemed fair and well placed enemies for the most part.
On the other side, i found a strange bug where some around 4 units wide black ribbons floated on top of some pools of water, there is still two or three too dark parts, and on the rooms that turns pitch black, there is some knights that are hugging the walls. Also, i expect the arrows and messages to be only for skill 0, they were excessive and annoying and made me think i was hand-held on those parts.
On the gameplay, i could say that i played it but not, who knows. I couldn't find the way to the nightmare entrance so passed on cheating and played on easy, which i regret so i'll be playing on skill 3 next.
I don't know if it is because its being ages since the last time i played on easy and that almost everytime i play on skill 2 or 3 that i couldn't get to it, and i found playing it uneventful. Due to this i played without energies or drive, without minding to explore or find much about the secrets or the details and just to see how it fared, relaxing so much that i almost died once.
So to summarize, due to all of that i have not much to say about the gameplay: it seems good for the most part, save some knights that can't reach the player due to some holes on the ground, one or two spikes of difficulty on the first half, and the overwhelming amount of ammo, being even more on the first half. You could have gone with a quarter of it and would be OK, as the map was practically littered with ammo. Also, even though it is easy difficulty, for a map this long you could have added one shambler only near the end for the feeling of accomplishment.
Going to play the real playthrough, on skill 2 or 3.
