If you've played the older version of super smash flash 2, you will notice that the bullets fly in a more realistic fashion, and appear to be coming from your hands. The screen shakes, and the targeting reticules move a little. This doesn't pose too much of a problem, but the enemies can still Dodge your attacks. This is one of the biggest issues with this game, as you constantly have to worry about getting hit by the bullets, which can lead to you taking damage and ending up unable to fight back against your opponents.
To overcome these problems, I suggest using a high end computer and downloading either the Windows or Mac compatible version of Super Smash Flash 2.0 apk. It works great on both computers and provides a better user experience than the older versions. Download it through the Google Play Store, install it and you're ready to compete against the top players of the land in high definition. It's a very challenging game with lots of content and can end up being addictive once you start playing. So to make sure you don't become addicted to playing, I would recommend downloading the version available through a high end computer software download site, as it will be easier to protect your computer from harmful programs and have a better gaming experience.
