Hi, I'm new to greenfoot.
I'm a lecturer and I like the way greenfoot allows to experiment with many variations and provide immediate feedback, on the other side.
I would to use greenfoot to provide some marked exercises too, and I would like to understand if greenfoot can provide a "frozen" environment, when the student can only insert code in a certain point, and then if its code make the game entity "win" then I can "record it" as a successful exercise in some automatic way.
