Love the use of Perlin noise world generation, would have enjoyed like mentioned elsewhere a small island and build up as you play. There audio for attacking was a little too much for me after a short period of playing, I simply turned the audio down a little and continued playing.
The sprites looked nice and the controls felt good albeit the attacking was odd and doesn't seem to work when standing still, I found myself having to move into the enemy whilst attacking to control the direction, not a huge issue, just needed to learn and practice the attacking/movement together.
