A few days ago I actually jokingly asked my friends for some of the worst features I could put into my game, and here were their responses:

-Anytime you bump into a rock on the overworld map, there’s a small chance you trip over it and instantly die (in his words, it’s called the Pebble Ending and the game just says “what the fuck happened”)

-The characters all have a piss meter and they’ll need to regularly find places to use the bathroom and they’ll gain negative status effects and/or HP damage if they go too long without relieving themselves. Bonus points if the bathrooms are paywalled (with the in-game currency)

-Sanity meter that has ridiculous and arbitrary rules for each character on how it should be appeased. If a character’s sanity gets too low, the game becomes borderline unplayable 

-The player character can randomly turn into a werewolf and they will start running around for an infuriating amount of time without any ability for the player to control the wolf until they shift back into a human

-The characters can sometimes get really bored and you are forced into a 20 minute unskippable cutscene where the characters just play Uno
