Plot bunnies for short games

Do any of you have trouble coming up with them?

Here's the thing: I'm working with an abs engine on my main game, and I'd like to make something short and RTP for practice. But...Dude, seems like every idea I come up with is some huge, multi-dungeon epic. The "small" ones are like 10 hours long. And even my short ideas end up fleshing themselves out into long ideas, it seems. I can't be the only person this happens to.

Hence, this thread. I've finally come up with a few things, but I could always use more ideas. I'm sure you could too!

So let's share! I mean basic ideas, not the exact character specifics. That way, we can all use them as inspiration for our own short works.

I'll start:
 

• A game in which you are a monster hunter and your little sister has wandered into a monster-filled cave while looking for you. Go in, solve the dungeon, kill the boss, grab the kid, yahtzee. A single-dungeon rescue mission.
• A game in which you are a kid trying to find your cat, which has wandered off. Go around town asking about it. Some people may want you to do things to help them before they'll help you. A short plot of many small, almost side-quests.
• A game in which you're a young guy trying to find a date for a festival. Go around town talking to people, find a girl you like, and win her heart. Do this by doing favors for her and talking to her, even giving her presents. Maybe do tasks for other people in order to get help or advice. Use a timer system so you only have a week to get the girl. A somewhat longer project with a nice dating-sim mechanic.

I have an easy time knowing where I want the game to go at the end, but a hard time figuring out how to get there.

For some short game ideas:

• A dragon is terrorizing a village.  The only problem?  The dragon is not vulnerable to weapons or magic.  What to do? 
• A gypsy put a curse on the player so s/he has 1 day to live.  The player must find the way to break the curse.

*The Big Bad has secretly unearthed a powerful artifact that will destroy the world in one day. You have exactly one day to become powerful and defeat the Big Bad. (This could use a time system like Vlue's.)

*Main Character wants to confess his love to a love interest, but other suitors are vying for her hand in marriage. You simply have to fight for the chance to ask her. (You could easily make this a morality thing, where if you search for peaceful solutions for each suitor, you're more likely to get the girl, but if you rely on brute force, she rejects you.)

* You are a young dog working hard to protect her oblivious human pack-mates from the dangers of squirrel spies, Llama assassins and the infamous barn cat that controls them all from the shadows. Along the way the humans impede your progress in their ignorance of the impending dangers all around them. (seriously need to finish this game sometime.)

* You are a plague doctor investigating rumors of a strange illness. Turns into a medieval zombie survival horror when you get trapped in the city affected and just keep running around surviving and trying to contain the outbreak until you eventually succumb to the disease yourself(little sandbox).

* You are a young girl raised by her father; a mercenary working for her(the child's) mother, who never had time for romance or family. The girl acts out often living where her 'mother' has complete authority yet no time for her, and ends up getting inadvertently involved in a dangerous job as a result where for the first time in her life she has a chance to confront and actually talk with her mother.

These are all the ideas I've ever tried to create for 'short games' yet somehow along the way I have this bad habit of letting them all go to far and then drop them when they stop being 'short side projects'. I clearly need more discipline, or a professional story condenser (or real word equivalent thereof).

My current collaboration project has a really simple plot -

You're a dead person stuck in a limbo world before rebirth. The limbo world is breaking apart due to excess of evil souls(demons), so the only way to be reborn is to purge the limbo world by hunting down all the demons.

Yes, this is exactly me! I have a pletora of fleshed out stories that would call for hour long games that I'm never actually gonna make, haha! Coming up with simple ideas is oddly a lot harder than it should be. I actually started practicing writing short stories a little while ago for this exact reason!

So let's see, ideas...

-You're the head of a tribe living in a snowy tundra which is soon going to be frosted over. You've got to find enough food and other essentials, aswell as a suitable shelter for your tribe before winter strikes.

-You're a very bored witch. All you want to do is go to the nearby village and turn all the villagers into frogs. That should put a stop to them hunting you down with torches and pitchforks.

-You're going to a an important meeting in thirty minutes, but wait, where did you put your car keys? You must find them quick, in time to make it to your meeting!

That's all I got off the top of my head, haha =P Proceeding to go to bed now, it's very late, lol.

-You're a young guy who has to go to bed. But oh no! The internet is distracting you! You must find a way to fight the urge to stay online, and get to bed! (Yeah okay, I'm really going to now, I swear, LOL).

How about:

-Your dad is a soldier fighting in the front lines, but has forgotten his lunch! You must wade through the hordes of enemies (You can't fight for nuts) avoiding cannons and other hazards to bring it to him.

-You suddenly find yourself trapped in a cave with no memory of why and how you got there. Escaping could be a puzzle game, while elements of mystery can be included.

-You've built a jetpack and put it on, but it goes out of control! Try not to crash into anything as you spiral out of control (Temple Run style)

-You want to bake a cake, but some bandits just raided your town and stole all the food. Go after them and either sneak your way to get your ingredients without them noticing or charge in and slaughter them all.

Hehe, I'll bite.

- A rooster gains the power of human intellect and magic. He then takes control of the farm and is trying to build an army to destroy the nearby village. You and two allies must charge in and stop the mayhem.

- A spider demoness kills your family and eventually you. With the help of a witch, you awaken in a new (stronger) body and hunt down and take revenge for your family.

- A fanatic opens a rift into your home city, unleashing demons everywhere. Find the fanatic, while fighting through the demons, close it and then leave whoever else to do the clean up.

- You end up eating too late at night and have a trippy nightmare but can't wake up! Find a way to get yourself awake and then not eat late at night.
