Shrek de Derde - Nintendo Wii

If you stand on the heads of enemies by jumping on them, sometimes you can't get away. This means that the enemies can hit you, but you can't hit them. This is quite inconvenient when you're standing on a group of enemies, because if they have a shield, you can only break it with a strong attack, but you need some more time to do that and while you're busy with that, enemies can hit you and then you stop loading that attack. So, that means you can't attack them, but they can attack you. So, avoid jumping on enemies unless absolutely necessary in Shrek the Third.
