Déjà Vu, the feeling of having seen or done something before. This is what the game is about, every 3 seconds a copy of yourself appears on screen and starts mimicking your past actions. Promnesiac is mouse-based, no keyboard input is required. The objective is to avoid hitting past generations of yourself. You earn points by moving further and more wildly across the screen, note though that every copy also earns points. Scoring a lot of points early on is a good idea as every time a new iteration starts you will get these points again. That is all there is to it. Go ahead, give it a try!
