Cool that you found ways to enjoy the game more! Just a note of caution to anyone reading this post, some of the items were restricted or removed for code reasons. The haste potion specifically can break the clock and make the game unstable. I don't want to discourage anyone from modding, in fact, I encourage it! Just a friendly note of caution.
The sword and phone don't "do" anything par se. The player starts with a sword, but will lose it within the first few passages (same time he loses his armor). The phone was just a joke item you can find while searching, but too many players mistook it for some kind of quest and were getting frustrated with how to use or unlock it - so I cut it out.
