Developer's Twist

1. When you finally beat a boss you've been struggling on, only to see that it has a second, even more difficult phase.

2. When a game, such as a platformer, is advertised as one genre only for it to be a different genre entirely in the actual game.

1. "Oh shit, this is a Developer's Twist kind of boss, isn't it?"

2. "The person who made this RPG pulled a Developer's Twist! I thought is was gonna be cute from the ads, but it's terrifying!"
