Now instead of crafting brick or wood, you create a generic block. Then seperately you choose what it should look like.

The block-tile types are:
Background (square with dotted lines) - these are just for decoration
Solid (solid square) - solid blocks
Platform (square with solid top) - you can jump through these and stand on them.
Eraser (square with an X) - this removes blocks

On the right side of the game you can select what it should look like.

Here are the block "recipes":
