In the download page, which one should I be downloading? I have an HP Windows computer but I'm not sure what a squirrel installer is. (I'm pretty new to this kind of stuff.)
I think the 64-bit Windows Squirrel versions are the ones for you :-) version 1.2.1 is a bit more stable than 2.0.0 but the new one lets you make platform games and shoot em ups as well as make games in color!
Squirrel is just an easy install version, double click the application and it will install it for you and start it automatically and create links on your Start menu. The other Windows versions just come as a zip file that you have to manage yourself.
