Slow game after a while :(

hi, i’m new as3

I’m making a game with as3, it is very simple, but when I almost have finished the first “beta” of my game i realized that it become slow later a while playing :frowning:

the game (2d) is only a ball (player) that shot mini balls against enemies that run to the player.

I have trying a lot of time to solve my problem by myself, but i couldn’t.
Only i can realize that the problem is about the creation of the enemies and mainly about the creation of the shots, this is created by a class called “scene” that through a addEventListener (Enter_frame), create and move this objects. After a while, when the game has created a lot of enemies and shots, the game begin to become slow; i delete the object and the variables with remove child and delete(), respectively but the problem continues.

Pleaseee , help me, i think that the things that the game creates aren’t completely deleted.

someone can explain me what happend and how i can solve that, some example maybe?
