This is beginning to look exactly like the final version which I pictured in my mind several years ago when i first discovered this game. The new biomes look fantastic and I could spend a lot of time walking the rocky beaches. I look forward to more sandy beaches in the future. There seems to be only an occasional sandy beach. Overall the landscape is diverse and the transitions are smooth. Sadly no caves yet but implementing those as well as (i hope still) underground biomes will be a pleasurable experience to explore.
The pseudo-dynamic water seems good so far. I dug straight down in the ocean and dug out a little cave and it handled the water additions very well.
