10 Games Hidden In Other Games

10. Rapunzel - Catherine

Catherine is an odd blend of a puzzle game, horror, and a tinge of dating sim. You play as a young man named Vincent, who struggles with his love life by day and then tries to survive deadly nightmares by night that continuously kill off unfaithful men around the city.

The gameplay loop and the platforming puzzles are both quite addictive, although some may complain that the game doesn't give you any means of practicing the tower-climbing sections in between Vincent's nightmares.

However, these people don't realize Rapunzel exists.

Rapunzel is an arcade machine hidden in the back of the bar that Vincent visits before each nightmare. The arcade is a 2D mini-game whose main purpose is to familiarize the player with some of the tactics that can prove useful in the real game, but if you play it for a little bit longer, you'll realize it's actually so much more! 

Despite the first few levels being tutorials, Rapunzel features dozens of unique levels, along with their own challenges and a story based off its namesake fairytale. 

It's basically a full 2D version of Catherine. In fact, it has so many levels, you can sink more hours into it than the game you technically paid for.
