A JSW author should be aware of the order in which objects are drawn:
1. elementary blocks (background, floor, wall and static nasty);
2. ramp and conveyor
3. the player
4. guardians
5. items
6. Maria or the toilet
( http://www.geocities.com/andrewbroad/spectrum/willy/collision.html
has a much more detailed explanation of collision-detection)

I believe that in JSW, Maria and the Toilet are actually drawn after Willy, but before the guardians (items being drawn last).

However, special objects (Eugene/Skylabs/vertical guardians/Kong/Solar Beam - although the latter doesn't have any infilled pixels so its collisions are attribute-based) are drawn after the items in MM - and then portals are the last thing to be drawn to the screen buffer before it is copied to the display file.
