(Like Encho, I'm also Brazilian, and my English is no good, so I'm sorry about that. I'm using Google Translate to communicate.)
The first idea I had when reading about this jam stuck in my mind, so I'll probably stick with it. It's pretty silly, but maybe it can result in fun scenes.
Basically, it's a game about platonic loves. The only move would be "Don't be pathetic!" or something like that. It's a little game about those kind of cool people who turn into complete failure in the presence of the person they love. :)
