Are you kidding me?
You can only unlock one of the points-based unlocks but not all previous? I got 11,000-something points and that unlocked the second medal but *NOT* the first one.
I then played the game again making sure to get 5000-ish points and then dying on purpose and that first medal didn't unlock either.
I'll try clearing cache and then trying again since obviously you can't unlock earlier medals when you've already gotten past them.
Who makes a points-based unlock system and then neglects to unlock all previous medals if a higher-medal is first awarded? Do you assume no one is naturally good from the start? Bad assumption.
