Well, I fought with a spear, a sword, a bow, put on different armor, but I didn't get past the first level :).
I'm not sure I understood how to get through it at all, on the other hand I could let the battlefield go for quite a long time :D. Maybe having some hints would have improved the situation, on the other hand there was a tutorial level which is cool! But there was so much text that I skipped half of it, don't hold it against me :).
It was fun to fight, although without balance :D. Congratulations!
