Thank you for updating the free demo!
I will definitely be buying the early access version as soon as it is available. I must admit I really want the latest version all the time but will make do with this till its ready for sale. Keep up the good work!
PS - if you release on the Unity asset store just the bits for weapon blocking and bending (just the basic weapon physics) I bet that will sell well and others can make their sword fighting games more realistic as well.
