Yeah, actually there is no block button in the current system. What you read is actually the changes for an old version of OJP Enhanced. All blocking is automatic and drains your DP (dodge point) meter as it you do it. The DP meter is that extra blue meter by your force point gage and when its gone, your start taking serious HP damage. To parry your opponent and not lose any DP, move into swings coming from the sides and move back for high swings and forward for low swings.
Read the "OJP_changes_enhanced" note pad for all of the recent changes and ignore the "OJP_sabersystem' notepad (its out of date, but still there for some reason)
Btw, Enhanced Version 0.0.6 is probably coming out tomarrow with a ton of bug fixes, so keep an eye on this site or on pcgamemods for its release.
