@tuffi: ok my sister found it. It was Lomax

Hello everyone!

My sister and I both remember a game we played on PC as we were kids, but couldn't find it anywhere.

I think we played it around 2004-2005. It's a jump & run adventure with side camera few game I think and the protagonist had a helmet with wings I think which can fall from the character's head and bounce around (when he deals damage I think).

I can't remember much details of the enemies or the protagonist, but I remember some of the levels in that game. The first few levels were in a forest I think (not sure if it was one lvl or more). What I'm sure of is that another lvl contained big red flowers with spring feathers as a flower stalk and you can jump to the background in the same lvl (I think in the background were dark clouds or something else gray). Another thing I remember is that a preview played after you wait in the title screen which showed a darker themed lvl with zombies (my sister says she remembers pirate zombies and a ship). The last thing I remember about the levels is that in the end of (some) lvls there are small bonus lvls where the protagonist was in a room filled with treasures where he can obtain gold within a time limit. I think there was a overworld map where you can check your progress in the game.

Thanks in advance!
