Rayman Legends can be played on the PC, using the keyboard, but overall it is a better experience to play the game using a controller that is paired to your PC.
You will be able to press the buttons faster and overall enjoy the game more as these type of platform games are mostly designed to be played using a controller, either on consoles or on the PC.
