I like this implementation. You added a lot more elements to make it look like a space shooter game. 👾

One thing I see that can improve is how many things you handle in each frame. Your FPS is very low at times.

A few things that can help keep that number up:

• The less things you do in every update call the better.
• There is a moveBG method you are calling, but if commented out, nothing really changes. Is it necessary?
• Instead of checking on every meteor on every frame if they are off screen, try running a sequence on each meteor instance, something like [moveTo, remove].
• There can be less if/else statements in the physics delegate method that checks the collision.
• Bring down the birthrate of your emitters. You can get a similar look with a much lower number and changing a few other properties.

Some of these should help with the FPS 👍🏼

Amazing feedback! Especially the [moveTo, remove], if/else on physics delegate. Will try to have as little things as possible in the method next time :)
