I think a lot of time can still be saved but a lot has to go right. My 2 other best times are a 1:18 and a 1:19.

I thought skipping armour and/or soul sphere would be extremely difficult but it wasn't as bad as I thought. I lower secret wall in the opening by yellow key to get an extra 25% health.

Overall the run was a decent pace as it's very easy to lose a lot of time in several sections.

That final mancubus is the worst.
