This is the first level I've played in a few weeks now, and I'm glad I did. It looks like you've nailed it for the most part, so you can send your resources my way.
I'm not a fan of autoscroll levels, but this one was very enjoyable for me. And like everyone else, I didn't find anything wrong with the level design.
I no longer have interest in SMW Hacking as I did when I first started several years ago.
