This is great! The amount of art and animation you did in the time is really impressive as well as all the dialogue etc. I think the animation especially is brilliant :D A couple of thoughts for future additions:
You could have one of the characters able to lay traps or blocks so that you can keep the ogres from one direction at bay while you fight the other side.
Maybe the ability to rearrange the fighters to protect the ones with low health would be good as you go along.
Obviously the goal at the moment is to live as long as possible and kill all the ogres, it might be good to have waves or a score to know how you're doing.
The fighters getting blessed with the spirit of dead comrades and becoming more powerful fits the theme really well, probably the best of all the games I've played so far as it's so well implemented! Great work!
Cheers
