Nah, when your character glows green and doesn't lose health, it means you did a "perfect block", and it happens if you press the block button right before the enemy's attack hits you. To do a parry, you need to hold the block button and press "up", and your character will do an animation that kind of looks like she's trying to push something away using her weapon.
Please try downloading the game from one of the links on the first page in the part that says "

this post, either way the "game freezing up after interacting with shiny objects" bug doesn't happen in either variants.
