2d side scroller/ platformer.
 

I have a very vague memory about this game... It played like a 2D sidescroller/platformer. Your main character was a punk rocker. First level was like a dark street/slums scenario. The second was a farm. Not even sure if it was commercial or simple shareware.

Sorry but that's all I can remember. Anyone remembers something like this?

It does not fit your exact description, but just maybe... Motorhead?

Graffiti Man?

Oh, jesus christ, I think that's it. I'll give it a go just to be sure. Still I'm almost certain this is it.

Greatest Irony is I love Motorhead, and had no idea Lemmy had his own video game.

*EDIT*

Yep, that's definitely it. I remember the guitar whacking move. Thank you so much. You just gave me a huge nostalgia rush. Game's not bad at all either. Pretty smooth controls for a 1 button beat 'em up, which kinda remind me the mechanics of Comix Zone. Beautiful graphics too.
