A feeling of infinity. This game doesn't explain everything that's going on. Which is just like reality. Ask someone in the street the history of the world and they'll forget things, things will be intentionally left out, it'll only be within that person's sphere of understanding. But I'm rambling.
Characters are for the most part multidimensional, and are gifted with fantastic voices.
I can't think of another furry game with such vocal perfection. As I said before, the sprites are less than perfect. Facial expressions, clothing design, and architecture are stunningly detailed, albeit pixelated. Again the atmosphere ignites the player. Such realistic and complex graphics have sheer energy, and that energy makes the player WANT to finish the game.
