Like You Would Really Do It: Kate's loyal, adorable dog Kevin inspires this in the climax after there was already a big debate about whether to use him as bait and the group found another option. Only it turns out that yes, Kevin is a goner this time.
Genius Bonus: Each game, all potions, rings, wands, and staves start out unidentified and being a random color/material. For example, a potion might be white, or yellow, or blue; a ring might be topaz or moonstone; a wand might be copper or titanium; a staff might be oak or avocado wood. In all four cases, one of the possible choices is a joke. One of the possible potion colors is plaid; one of the possible ring gemstones is kryptonite; one of the possible wand metals is mercury (try holding up a wand made out of a metal that's liquid at room temperature!); and one of the possible staff materials is fall (a "fall staff", get it?).
Good Bad Bugs: The PC version had some notable bugs that allowed a savvy player to cheat, as explained on the Roguelike page.
