The game wast JUST like Strike Force Heroes and Raze. From lvl selecting, gameplay was the same, BUT it had medieval style. Swords, bows, shields. I remember in the begging of the game your father was getting killed by the main villain.
only thing that I could find that matches 2D platforming like sfh/raze in medieval setting and were the intro has a cutscene with a father is this:
Arcane the armor collector
Hope it's that. Doesn't seem to be on armorgames though, but a google image search can quickly show you if it's the game you're looking for.
