I have an idea for a game where everything is made out of paper. I wrote about it before somewhere on here but I can't find it.
Anyway, you play as a little paper boy or girl with a bow and matches for arrows. You travel a world where animals and plants look like origamis. As you explore, you'll find useful items such as wax, water, and oil. These will help you battle enemies. For example, you encounter a giant spider in a cave. You first throw oil on it, then send a match with your bow to light it on fire. It can also be used to look through paper or camouflage yourself, though that makes you very susceptible to fire. Wax allows you to swim or make a boat in order to cross a lake. Water can crumple structures or enemies.
You'll find other useful items like scissors, paint, and paper. It's obvious how scissors could be useful in a paper world, and it basically acts like your sword or axe. Paint is used to tame animals; you injure them so you can approach them and draw a smile on their face - which makes them good now of course. Paper allows you to build structures yourself but can also make copies of yourself or animals you've tamed.
There's weather in the world (although no rain) and a heavy breeze could send you flying. Instead of rain, it "rains" little paper droplets.
As for the story, it's about a child looking to a find the cardboard forest or something stupid like that.
Graphical style could look like this:
