I kind of ran out of time on this piece, ERK. :c
Thanks! I had a lot of fun making Mario, but yeah, the background and tiles definitely need work.
The characters I like, the rest of the piece, not quite sure. Good effort.
I use an odd pixel height for the tiles; 23 for width and 20 for the height.
I don't understand this, but I appreciate the effort.
I aim to confuse. :)
Bit of a hard read
