I finally saw Indie Game: The Movie.
It was oddly reassuring.
Some game ideas I've been kicking around:
» An Adventure Time, Venture Bros., or Archer arcade beat 'em up game à la Konami's Teenage Mutant Ninja Turtles, The Simpsons, and X-Men.
» A platform game in which you play as a man who suffers from multiple personality disorder. Instead of power-ups, each personality possesses different abilities, and you gain increasing control over the personalities as the game progresses.
» Poker played with UNO cards.
