This is going to advertise version 3.

Since none (or not many) of you probably played the original two, I'm not going to bother pointing out the updated stuff because... well, what's the point? 

Basically, it's a semi-Pong game that is Metroid themed. It also incorporates a few features from the Metroid games.

All sprites and sounds/music are from the original Metroid game from 1987.

And I left credits at the end of the game, so no complaining about there being no credits!

Also, if it's a bit laggy, it's your computer. It runs fine on mine. But if the lag is unbearable, try downloading it.
