Commander Keen in Aliens Ate My Baby Sitter!

About

A mean bunch of hungry aliens have your babysitter and they're planning to make her their main course. Now it's up to you, as Billy's alter ego Commander Keen, to climb into your homemade Megarocket and save her. Or risk explaining what happened to your parents. The only question is: Can you complete your mission before dinnertime?
