Honestly this run is very good though, everything was very solid I think. The only real "tech" that I use is when opening doors, they don't have any collision. This means you just go right through the door after opening them, thus saving a bit of time.

The biggest optimizations available:

• Enter the Debt Box Puzzle combination faster. I'm sure you can speed it up a bit by being more risky. It's just so difficult due to having no reticle in this game to know where you are pointing.
