LÖVE

To use the love2d particle system, you must first create the particle system, assign an image to it, set a lot of properties for the particle system and FINALLY update it in your update loop.

It's quite troublesome, but very flexible. Check the love2d wiki, it has a nice guide on this.

I made that, but tried to fixed this problem:



Changelog:
- Now the player start in the middle
- Restart button fixed
- adding particle system

Bugs
- Particle System dont show in collision place
- The player collides with the map only on one side

Ideias:
- Adding menu and maybe final credits
- Graphics Filters
- Enemy shoot in high level/waves

To fix character going out of the screen sides, just check if the the playerX is not bigger than the (screenSizeWidth - playerImage:getWidth()) or smaller than 0.

Obs: playerImage is the texture the player uses, and i assume you're drawing the player without setting an offset.

For a first invaders it looks and sounds nice (yay for non-black background!) The collision detection is off though, the left side of the enemies ignore bullets.

Well you said:

You can modify what you want

Sooo.... I dinked around with your code
.
Would be beneficial for you to fragment your code into modules - easier to add feathers and easier to maintain.

Mods I made are only an indication as to what you could do if you want - not taking credit for you codes.

Best
