A survival crafting game where the tech tree goes backwards. You start in a prepper hole with working water filtration, food sources, etc, and everything is nice. Then something breaks and maybe you fix it. Something else breaks and maybe you fix that. Three things break at once, and at least one of them is going to stay broken. Have to do something more primative and time consuming.

Eventually, enough things break that it’s no longer sustainable and you die. Game ranks you based on how long you last.

I’m thinking an RPG Maker style game. You play as Morpheus, the god of dreams. Each level is a different person’s dream. When you arrive the dream is a nightmare fueled by past experiences and internal feelings. You have to journey through the dreamscape and find these factors and resolve them to heal the psyche of the dreamer and turn the nightmare into a good dream.

An example would be a dream where the dreamer is delivering a presentation in front of a classroom naked while the other kids and teacher make fun of them. As that scene plays out, you walk around the school and discover little tidbits about the dreamer. Some of these tidbits are external factors that led to the dream, like memories of people making the dreamer embarrassed for being themselves. You could resolve these by fighting and defeating them in the form of nightmare creatures. And some of the tidbits will be internal factors, like feelings of insecurity and defense mechanisms like reinforcing ideas, that give power to the twisted logic of the dream. These, you have to heal by pointing out the flawed logic and encouraging the dreamer to accept themselves. Once you do everything, you go back to the classroom and find the dreamer giving a TED talk to an enraptured and admiring crowd.
