Hey! Thanks for the typo report, I'll have it fixed by the next release!
The bug with some two handed weapons not working as intended is something I'm aware of but I'm not sure how to fix yet. For now I was hoping that no one would notice!
I'll try to address it at some point when I get a bit better at Ruby Script.
It might might be hard to get EVERY item in the game as there was a unique silver sword that dropped from Victor (the guard that accompanied Furo at the start of the game) and Victor leaves if not conversed with the first time you appear in Emerald Forest. Plus he only has a 5% chance to drop it and can only be fought once. Plus, Edgy Knuckles and Gaudy Ring are mutually exclusive with Snuffles at the start of the game. You can also Pickpocket a unique accessory from Saffron but she only has a 5% chance of getting it stolen. Victor also had a rare ring you could steal from him if you managed to convince him to stick around at the start of the game.
