I have tried a lot of stuff, and I believe Lego Marvel Super Heroes (or other similar Lego games) are absolutely perfect for a small kid. There are infinite lives, and you can play co-op where you can do all the hard stuff while they enjoy the ride. Eventually they will learn by seeing you do stuff, and they will learn and want to do it too. It is truly amazing, a very forgiving game for a 4yo. As a side note, my son learned this using a fight stick, since "move the stick in that direction to make your character go to that direction" is easier for them to comprehend and associate than using a dpad. Also way easier to hold with hittle hands.
