Hi! I’m doing well, thanks!
If you mean the example scenes shown in the screenshots, I built them using the assets at their native 16x16 resolution, aligned to a 16x16 grid. Then I scaled the final image up using nearest-neighbor / no interpolation, so the pixels stay perfectly sharp.
So you don’t need to resize the individual assets. Build everything at the original 16x16 scale and, if you want a larger image, upscale the whole scene by an integer amount like 2x, 3x or 4x.
