Hey Ania,

This is the error running your unadulterated code with the exception that I corrected the link to the css file in the html file.

Uncaught TypeError: can't access property "classList", squares[currentLaserIndex] is undefined
moveLaser https://fishbite.github.io/space-invaders/app.js:107
setInterval handlershoot https://fishbite.github.io/space-invaders/app.js:130
EventListener.handleEvent https://fishbite.github.io/space-invaders/app.js:134
app.js:107:5

It occurs when the laser shot exits the top of the screen and I'm not sure how to fix it!!! Any ideas?

Thanks for the video tutorial BTW. It's much appreciated by many folks out there especially myself :)
