Fluidity on Nintendo’s WiiWare may be best game I’ve played all year. My only criticism is that the plot is thin – the main character is a puddle, supporting cast is a book and the enemies are flaming slugs made of ink. However, Fluidity is a puzzle game. The plot doesn’t need to be strong, the puzzles do. I’ve only played for 2 and half hours so far, but in that time no two puzzles were alike.
