I noticed that the SDA run of this game has not been posted here and it appears to be faster than any of these times. I wanted to add the time myself, but I cannot submit it.

This is any% singles. I measured the real-time as a 1:13:45, IGT 1:14:55.

I agree this has to be submitted, but I don't know if this is the moderators' wish ^^'
