suggestions from me and friends:
ability to kick
smacking while empty-handed
spawn enemy button
ragdoll button
stamina system: to prevent people from cheesing the combat by flailing their arm around randomly.

I like the physics based swinging a lot, being able to control my swords direction myself is great. It's something a lot of games just don't have. I don't know if you plan on keeping it this way, but it definitely works, especially if there was stamina as well.
Love the project so far, honestly I'm having more fun with this than a lot of stuff I've been playing recently. Look forward to seeing its future.
