thank you for such a wonderful game. :) I would recommend that you add the same block shapes for most if not all block types to allow for a much prettier construction system. especially things like Wooden blocks. if anything the wooden blocks should have the most variety of shapes as wood is much more pliable than any other block type. this would allow things like less blocky looking roofing as we would have upside down ramps and wedges. I understand the need for "progression" but shapes should not be that progression. it isn't that way in real life and should be available to use in game as well as it makes the building experience far superior.
