So, Sim, I get you're busy with 9bitmmo, but what I'm asking of is rather small, I just want some new blocks.
First and foremost, what I REALLY want, is a proper blue block, blue plastic is far too light and nearly indistinguishable from the teal plastic and of course I'm not asking you to change the color of blue plastic, as that would mess up all kinds of pixel arts and builds, but rather that you add a "dark blue plastic" that's about the same color as the side of the pubpad.
Next: black and white plastics. So you probably haven't heard much of a petition for white plastic, but I'm suggesting this anyways because snow buildings are vulnerable to oven vandalism, however, I know lots of people want a black plastic, as the only current solid black block is black tile which is a hefty 20 gold a piece, which can be very hard on the wallet when you want to make a mostly black pixel art.
More carpet colors: blue, orange, black, white, maybe some with different outlining? I'm not quite so enthusiastic about new carpet colors, but I think they'd make a nice addition
More full size blocks: Full size plastic would be very nice, and full size carpet too, since although it's intended for flooring it's used as a building material anyways .
If any of you have suggestions for new blocks then feel free to post below.
