Pits should be visibly marked.

I mentioned this before. The issue is there is no easy way to tell when a 
vertical shaft leads to 
safely and when it leads to falling off the world. This is really frustrating 
because it makes every 
leap of faith an unknown.  Mario doesn't have this issue because the levels are 
generally 1 screen 
high except when you unlock secrets (like using the tanuki suit to fly off the 
top of the screen).  

Suggestion:

1) Don't have vertical scrolling on levels that have holes in the bottom of the 
world or to put it the 
opposite way. If you want to make a level with holes off the bottom of the 
world make it a 1 
screen high level.

2) If your designers are not disciplined enough to do that, then instead of 
holes use lava, fire, 
spikes.  Lava has one advantage in that you can add "glow" tiles above the lava 
to warn the player 
that it's a death pit making them less a leap of faith.

I like the second idea, however you may not even need to go that far; It may be 
sufficient to just darken the tiles above bottomless pits.
