This ended up being a nice little game. It was fun to follow your dev logs as well.
Sprites were clear and readable, as were the animations. Unlike Giggs, I had 150 denarii by the time I needed it. Guess I just killed errybody that got in my way.
I didn't find the kick very useful. Considering it being a sequel to 300, I think it might have been more effective to make the kick a super weapon that would get powered up as the player gets kills. Kicking would kick everything into slow motion like the film. Add some compressed "THIS IS SPARTA!" VO on top would be the cherry.
Anyway, I had fun, and was able to make it all the way through. Nice work!
