When you lose an item near a door (like the helmet in samus level) just leave and enter the area and the item appears again. Doors are cool because they reset some stuff once you exit and enter them |
Yeah I know, it was faster to rush through the beginning than go back :) Plus the fire flowers don't reset.
I use doors all over to reset puzzles. The hard part is getting stuff not to reset when making a puzzle. Items (you lost) already reset a few blocks off screen, you don't need a door. Although you can use doors for item duping in some cases. Take one with you through a door and go back for a second copy. Works with helmets, one on your head and one in your hand from a single one laying on the floor.
