An idea for each LD25 theme

Spent maybe about an hour last night going through the list of every possible theme for Ludum Dare 25, and designing a game idea for each. Here are the results:

Swarm
Direct a swarm of bees with the mouse. Sting predators and people enough to protect the hive, but not so much that all the bees are dead.
Shadows
Move things around to make sure something is always in shadow, so nobody sees it.
Parallel Worlds
Platformer where every time you die, play switches to a ‘parallel world’, where things are very slightly different. Gradually things get very strange.
Reincarnation
Hmmm, kind-of covered this with the above. Maybe instead, each time you come back as a different character, with different abilities. Birds can fly. Trees just slowly grow towards the goal.
Surveillance
Tower-defence-like where you set-up security for a museum exhibit, then have no control while thieves try to break in.
Trapped
You are stuck in a bathroom (or some other room, maybe). You must survive until somebody realises and rescues you. Find things to eat, drink, keep you from going insane from boredom. Plays-out in real time?
Collapsing
Platformer where each time you reach a goal, part of the folds up, giving you a new challenge.
Infection
RTS where you play as the immune system
you cannot see viruses, only the dead cells from when they errupt. You must control the spread of infection for long enough to develop antibodies, while causing as little damage as possible.
Disaster
Play as a rescue worker after an earthquake. You can only hear any survivors when they are very close, each will only live for so long, and you do not know where they are or how many there are. Game ends when you choose to stop searching.
End of the World
There is a huge asteroid heading for Earth, and you must do your best to prevent it colliding and wiping out all life. You cannot win, and the game will not let you play for a second time.
Outer Space
You listen out for radio messages from space. Sometimes you receive one, but it is from so far away that it would be impossible to communicate back.
Construction
Reverse Tetris. Attempt to build the tallest skyscraper out of tetrominoes, without ever creating a line of 5 squares, or they will disappear and the tower will collapse.
Powerless
Adventure-style game where there is a problem presented to you, however despite lots of seemingly-possible solutions, there is actually no way to win and you lose.
Chaos
Game about chaos theory. You are trying to collect small pieces of paper that you have dropped, but every time you move they scatter. I don’t like this idea, but I can’t think of anything else for ‘Chaos’.
Colonize
Play as mould in a house. People will spray you if you are too obvious, so grow in the shadows to build your strength.
Absorb
RPG where every time another character speaks about you, their words affect your stats, like buffs/debuffs.
Inside
Visual novel where you are falsely imprisoned. Avoid attracting negative attention. You can attempt to escape, if you wish.
Stranded
You are like ET, accidentally left alone on an unfamiliar world. Survive until your family return for you. Who do you trust? Gradually learn the language and culture.
Afterlife
RPG where after death, you return as a ghost and can attempt to guide your successor.
Destruction
Sneak into buildings in order to set them on fire. After you are eventually caught, you are taken to court and it is revealed to you how many people died because of your actions.
Invasion
You are a mind-controlling alien. Your aim is to brainwash all the humans in each level, without anybody getting suspicious and alerting the authorities.
Old vs New
Work as an art expert, and identify subtle differences between originals and fakes. Criminals will bribe you if you can convince your boss that a fake is real.
Inverse World
Go through a life backwards, making sure that events line-up with what has already happened.
Mirrors
Identify vampires by attempting to look at them in a mirror. The vampires are wise to this, and will make efforts not to go near reflective objects.
Quarantine
Play a government during a deadly epidemic. Each day, you get a map of how the disease has spread, and you choose where the quarantine will go. It takes time to set-up the quarantine, so it is easy for the disease to escape. Anyone in the quarantine area will be gassed. Save as many people as possible.
Night and Day
Play as a superhero. Stop as much crime as you can, while also not losing your job.
The End is the Beginning
Game starts at a funeral. Guide the protagonist through the stages of grief.
Migration
Flight sim where you are a bird. Carefully manage your energy, keeping in position behind another bird to slipstream.
Deception
You have several different fake identities. Avoid mixing these up and telling lies from other identities.
Guardian
An entire game composed of escort missions, because everyone loves those. After each, the person you were escorting is killed stupidly in a cutscene. See if anyone actually finishes the game.
Unstoppable
Your car can no longer brake. Drive through a busy city killing as few people as possible.
Science
Working as a school chemistry teacher, manufacture and sell drugs and other illegal substances without anyone finding out. If someone starts to suspect you, you must poison them.
Claustrophobia
Turn-based puzzle game, where you navigate through a crowd without ever becoming surrounded and unable to move.
Ghosts
You are a ghost in a big house. People keep moving in, and you must convince them they are insane by moving things around when they are not looking. If they see you enough, they call in the ghostbusters and you lose.
Time Loop
Navigate through levels by entering x commands, which are then repeated over and over.
Mind Control
Transfer your conciousness to other people in order to open doors and perform tasks. However, while controlling someone else, you must press certain keys to make sure that your real body continues to breathe.
Fortress
Manage a besieged fortress for as long as possible, with the problem that you must occasionally open your gates for pizza delivery men.
Transformation
Defeat a series of obstacles, each time by choosing an item to be transformed into a cat.
Dystopia
Keep your citizens in fear of you enough that they dare not rebel. This is done by bluffing in official speeches. If you are caught, fear drops and you risk a rebellion.
Alter Ego
You are a werewolf. Each day, carefully arrange things so that you don’t harm your family in werewolf form during the night. (eg, leave a steak out, but with sleeping pills in, so that you eat that.)
Symbiosis
You can choose to give a symbiotic organism various amounts of your food. The bigger it gets, the more it benefits you, but if it gets much larger than you it may turn on you.
You Are The Villain
This was the theme, can’t be bothered.
Survival
Most of these ideas are already about survival… Maybe, you are an ambulance driver, and must get to people as quickly as possible but without crashing. Sometimes you do not have enough time before a person dies, and it is impossible to be fast enough to save them.
Growth
Run a plant nursery, genetically modifying plants for desirable traits, and potentially unleashing a plague of deadly mutant vegetables.
Ocean
You are the ocean. Manipulate your waves to guide little boats to the shore.
Journey
Navigate through an unfamiliar area with only a misleading sat-nav.
Underworld
Wander through sewers, uncovering personal items that people had lost. And sewage.
Salvage
Search through a rubbish tip for anything with value, that you can sell to buy food for your family. Time limited, and you can only carry so much at a time.

I’m particularly pleased with my idea for Absorb. I’ve been wanting to make a game about mental illness for a long time, and that would work well as a mechanic to include.
