Android APK signing

Question

I'm not really sure how the APK signing is supposed to work really, so I thought I'd ask here and see if others might be willing to impart some advice.

When signing with Unity, I have a keystore setup (took me a bit of digging around on the web, but I got it). Should this keystore be used for everything or just for this one game?

Also, there are the public and private keys that I need to sign with a particular password. Should these be the same, different, or is it mostly irrelevant? Also, does one or more of these need to change between projects?

Sorry to be such a noob on this, but I'm mostly used to internal corporate development, where signing just doesn't ever take place.

Thanks much in advance for any and all advice anyone can provide.

@kimstock thats not an answer, use comments or even better, ask your own question for help.

@Nekoyoubi you use it for that particular game - most generally, and its VERY important you remember that password information later, TRUST ME! write that keystore password/username password down!

now as for making a single game, you use a single signature (keystore, all that stuff) and when you make another unique game (or sequel or expansion pack...idk) then you use a different keystore and password and such...and again DO NOT FORGET THAT PASSWORD OR YOUR APP MUST BE RE-UPLOADED THUS LOSING ALL DOWNLOADS (atleast the figure of your downloads) AND FORCING YOU TO USE A NEW KEYSTORE!!! I cant stress this enough!
