You and your shadow are inseparable but with a difficult task ahead. Many levels are prepared for you in Alter Ego where word “classic” gets new dimension.
Platformer? Yes a bit but you cannot jump there. The only possibility is to climb, move and solve puzzle tasks. The goal is getting all the special points and avoiding enemies. More and more content make the game quite dynamic, for example disappearing ground, different points and need to switch the places with your shadow. Some levels are really tough but everything can be beaten.
