my game is slowing down the longer i am on layout!

my layout start out normally but in the matter of about 10 second slows down, idk if it has anything to do with how huge the layout is or if it is because i got many sprite there or in general. maybe a little list on what could cause it would be helpfull?

Also make sure you remove things that are off screen and wont be coming back. No point to have a bullet you dodge fly around forever

I tried with the Debugger and it works okay, although the actions of my characters are does the actions when keys reliased, which it is are not supposed to do.

If you set your actions to happen on key pressed and they are doing it on release, you most likely have other code that is still interacting and making it seem buggy.

It is hard to guess at what that could be without seeing your code though.

ill show a screenshoot when i can
