Oh man... this is so awesome, I like how they still improve kinda major mechanics in one of the final updates!
My opinions on everything I've seen:
-The water ofcourse, looks way smoother! And just feels... better. For me I gotta get used to it tho, but that will happen quite soon I guess!
-Vine Rope, a way to get ropes even sooner, nice addition!
-The "Gallaxtic?" dye in the before video, I LOVE how it moves slower on the inside then the outside, always been a huge fan of that concept!
-The Golden dye in the after video, besides looking sweet as hell, the thing I love the most is the way it reflects the light from the torches on it from diffrent angles, I hope is the case with more dye, because that looks just incredibly good!
Awesome spoilers, bring some more soon!
