Okay thanks for all the feedback.
The gameplay will be just as good as the original, if not better - that is my goal, to keep the classic gameplay STYLE of the map, obviously there will be minor variations, but all the jumps will be the same as well as most of the lines
I am placing the terrain in a way that BENEFITS gameplay.
Also, in the cave, there are all clip brushes, you cannot get stuck on anything at all, basically, I am clipping out the details, so that's all they are - details, then putting clip brushes where the walls would be on the original sewer - same gameplay, but far better experience. This is not to say that there won't be any variation.
Yeah jitspoe, I took a look at them sewers, they don't look as good as a cave imo, + where did the water of them sewers go? Into nowhere? That's not realistic - water randomly vanishing.
I was thinking of placing snow spots along edges etc, to give it a wintry theme based on the feedback I got from clipz. So thus, the ice in the cave is not random.
The cave holds up by the wood, it's just dirt has gradually mounted and fallen down from the sides from all the people bashing into the wall... (hence the crack in the wood).
If you saw the map, you'd see that it looks like wood is holding the tunnel up, but dirt has fallen over it
