At first, you will not notice anything different with the terrain, except that it will seem a little higher, this has a reason, as any cell now is a block, meaning, each layer can be mined/digged, the height is no longer a visual height anymore, its actual layers sitting on top of each other. look at our old main menu image (the image in the front website), this is how it looks, also, the water looks more or less like the water in that image.
Each strength level of the water now has a fitting "block". the one here is the medium strength water block:

each layer is the roof for the next layer, so its possible to mine into a mountain instead of digging down. also, digging is different now, it isnt a black cell which appear to be dug, its an actual hole in the terrain. mind you, townies can fall to their death if they fall more than 2 blocks high (they wont fall easily, someone need to mine they terrain they are standing on), so it will always be safer to just dig ladders down and mine the blocks. also, since the water push monster and townies away from them, when we add flood gates, you could essentially build a water trap that will drive monster off high cliffs.
we have 8 new types of stairs which look like proper stairs now and that function bit differently.

we have already began testing floating islands that will house certain rare plants and creatures. i must say, early tests show great promise of those and my mind keep shooting new possibilities for the creatures/plants you could encounter on them.

Townies can mine blocks that are on top of them, so you can now not only dig down, but also mine your way up.
what else? many more which i dont wanna jinx yet, but i can quite positively say - the next patch is going to be big. thats why it will also take us more time to release it. stay patient.
Note: the following is not representive of what we have now! it is looking better now, with slopes and all
