Great, what you have written is the second way to handle sprites, through lists and, as you have pointed, may save time compared to browsing a finite buffer in which you will have only 1/10 filled in with sprites.

There are two ways to handle it:
1. when you add an enemy:
1.1 browse the list and find the first empty member of the list, add it there
1.2 append it to the existing list

2. when you kill an enemy (object, whatever)
2.1 set a special value (let's say -1) to the list member to set it available
2.2 change pointers (tell member-1 that next member is member+1 and not member)
2.3 shift member list (member << member+1 << member+2)

You can go with lists. That trick is often used by software programmers.
