Killed two dragons, third one killed me. TIP: remember that armor also replenishes you're health. Use it when low on health (less then half). Around lvl 10 stop you're weapon craving and go for the armor. Get the divine edge and wait for a dragon.
Nice game, quite difficult for the hard badge. Here's how I did it:
First cut of his legs, then try to cut of the arms while standing up.
If you did this and didn't die you must have had about a 100 spikes already.
keep on the ground while searching for openings in the spikes falling.
It took me about 10 minutes.
Post Scriptum: It might help listening to Dave Dumbreck - Take five.
Meshuggah, Aerosmith and Billy Talent didn't help much
