Thats usually how climbing works in most vr games and the boss fights can be skipped if you spam your grenades
Skipped how? I must have hit her with over 10+ grenades, and yet she was still standing. Kind of nuts how we were invincible until the boss fight. There should be an option that lets you skip everything to get to the end (most likely add a code or something after beating it the first time to get to the end).
EDIT: Either skip all the fights or, at the very least, skip to the final boss fight.
