Making 2d Game Which Looks 3d

I wonder if I can make a 2d game which looks like 3d or not? There is an example but I can’t recognized whether it is 3d or 2d.

Please check the 15th second. There is a game and looks like 3d. Can you tell me whether it is 3d or 2d? I mean can I make a game like that by using adobe illustrater?
