"Anna" is an adventure game designed to analyze what the player does and react around his behavior. It features three ending according to how much the character has gone deep into madness. The more you play, the more you find, but to really discover everything, you'll have to lose yourself. With the game, you'll also get the main character's notepad, giving you more insights on the plot, and the original Soundtrack.
Great game but too short. Mostly what made it somewhat lengthy is that it's hard to figure out what to do..
