It is a game, but it's a relatively loose one compared to something like a lot of mainstream role-playing games or board games. It's more akin to cooperative storytelling where you're making a story together, with the rules to provide prompts and suggestions about where they story should go next. As you might suspect, it's pretty loose; IMO, it probably wouldn't fit the theme to be shuffling miniatures around or counting up XP.
I admit this isn't probably a good introduction to role-playing games, particularly the "storygame" kind, if you're not familiar, as it was written pretty off-the-cuff. I'd suggest around two to five players running punks and one player running the system.
If you have specific questions, just let me know, and thanks for giving it a look!
