I also appreciate the layout of the level itself, it feels very Mario-like and very authentic. All except for one bit. The gimmicky chainsaw elevator. I understand the concept behind it, but taking damage causes Mario and the platform to freeze while the chainsaw to keep on moving and messes up the chainsaw's pattern, resulting in you taking damage from the giant fireballs overhead because of the slight timing error caused there. And even if it worked perfectly, I have to say that it just wasn't that fun. It didn't add anything whatsoever to the level, and just felt like a last minute gimmicky add-on. I think skipping the chainsaw segment and warping the player to the spot where the chainsaw part warps to would be better.
From what you described, it appears you played the oldest version. The newest version in the post before yours has a completely overhauled elevator without giant fireballs.
