Finding a Game Idea

I'm an intern in a game development company. During the internship, I'm going to do my own project.

First I needed to find a game idea and I started to think. Finding a game idea from scratch is REALLY HARD. Nothing came to my mind. Then, I decided to choose a theme and make a game on that theme. I went this site and "Ice/Igloo" came out as a theme. I got rid of the "igloo" part because I thought that it was very specific. I needed more general theme. 

I chose an ice cube for the main character. And I started to think about how the base mechanics is going to be. When we control the ice cube, If we press left for example, it's going to keep continue to go in that direction because of slippery surface of the ice cube. And the ice cube is going to melt, so we have to finish the level without melting completely.

After the base mechanics, I thought the story and found this:

Every ice cubes want to get rid of their ice cube tray and be free. The heaven for them is the north pole. They can enjoy the freedom in there without the idea of being in someone's drink.

Our character is also chasing this dream.

But it’s not that easy. You have to be so lucky. You have to wait somebody to cool his drink and take an ice cube. When he tries to take out, you have to pop out and run away instantly before the guy gets you.

After all that stressful experience, a new adventure is going to begin for you. You need to go north pole before melting completely. Also you’re going to have hard times with moving because of your slippery surface. There will be some traps which make you melt so fast. You need to be careful.

After all that difficulties, you are going to get your freedom.

(I think the story is not too bad.)

Here are the other decisions and thoughts:

• I'm having trouble designing the levels and making these levels hard.
• I tried to write high-level design document. Some part of it was really boring. It is still uncompleted.
• I'll make this game in Flixel. (Making 2D game in Unity is really painful.) For the map editor I'll use Dame.
