Seriously this is solid.
The graphics for it being a 48 hour game jam are quite out there, wonderful job with the lighting and effects, hell even the animations.
Slightly frustrating getting knocked off, but I understand that is the main way the enemies can kill you.
The variety of weapons and shields was awesome for the 48 hour limit, I can tell sound effects were probably a "Nice to have" but would have been nice to have some ambiance and some attack skills and what not.
In 48 hours you achieved this, I'm curious to see what a week / month would end up being.
Really good job.
