I have been aware of the first trick of seeing the code from OOB, but I couldn't manage to use it quickly to get a good score so I didn't think it would be worth bringing up. However, with enough practice and good RNG I believe it could definitely lead to good scores.
As for the Goldbar clip, unfortunately it sounds better than it really is. Looking at the categories that require the Goldbar, we have All Items, Greedy Thief (Not sure about that one to be completely honest), and 100%. In All Items, there is a decent chance one of your items will spawn in the Office, which means you'd need to go into it regardless. In Greedy Thief and 100%, you need all of the money from the safe, AND you need the money stack from the Office. This means that All Items is the only category which could benefit from this trick. But let's say you manage to get a run where no items spawn in the Office, and you decide to go for the Goldbar clip; not only did you say that it's inconsistent to get it out first try, but you also mentioned it has the potential to pop into another room, or OOB, this makes the chances of successfully landing a run like this with speed very low. At the moment this trick seems too unlikely and too inconsistent to actually work unfortunately.
Regardless of all my negativity, I do have very high hopes for both of these tricks, and I think it's also great to see some activity in the community. Thank you for bringing this to light!
Edit: I will also look into the Goldbar clip trick and see if I can find a consistent setup and I'll keep everyone updated
Exactly, there are specific times where it could end up being great, and that's exactly why I have very high hopes. And don't worry about overlooking some things! As you said, you don't run this game, so it's completely understandable.
