Spider Invaders

This is my second game, i've spent some time on it.

You are a spider killing flies with your toxic web, level up to get upgrades and get a highscore!

I would like some feedback, also i know the main GamePlay scene is quite empty, didn't know what to do with it...

All Art and programming was created by me.

Music was taken from the internet:
