Have you missed games from the past, with flash elements? Do not be sad – you can still find online entertainment with similar features. Consider Paper Planet 2, a cool adventure where you will defend a planet. Your planet will be attacked with different weapons. Your aim is to shoot and stop all the evil objects that are moving in your direction. Every time you earn points and can use these to upgrade your defending potential. Make sure not to miss too many attacks or the planet will be ruined!
