Stopped clock slightly late, you can see a black screen with 1:02:22 easily. 460 points shown at end.

This was all possible to nad_chario's routing, where he skipped Marie on Day 2. This is because on Day 4 you must call a nurse and wait, so he gives her the Day 2 items while waiting for the nurse on Day 4. Because he avoids Marie on Day 2, he never gives her a kiss until AFTER the locket, which fixes the bug in the game that would normally only give 450 points (for some reason if the locket is the last item given, you will not get the 10 points you should).
