Canvas 13b was a limited-time 100x100 pixel canvas with a very short 5/8 second cooldown timer that was made available while the pxls.space server was migrated to a different computer.
This canvas saw several changes in gameplay:
A much shorter, 5 second, cooldown timer (8 seconds for pixels that were previously placed)
Palette changes - first black/white (accompanied by the message "sorry i was too lazy to convert the color hex codes to grayscale"), then greyscale ("I heard you like retro"), then two iterations of the regular colors with a pink haze
No username lookups for pixels. The username shown for each pixel looked up was simply -snip-
The latter was a side-effect of the temporary canvas; setting up user registrations would have been cumbersome for a canvas that was expected to last only as long as it would take to migrate the server. As a result, each 'account' was merely an IP address, which was thus shielded from other players by forcing the username to '-snip-'.
Due to the canvas's small size, low timers, and essentially anonymous pixel placement, many fights erupted on this canvas. It is the first canvas on pxls.space where the Green Lattice ended up having no presence by the end.
The final canvas state is one that is heavy on flags, backgrounds, and low on art - mostly art that was defended from early in the canvas's time.
