@Entity1037, I am not having any problems with any of the keys Also, I have to updated this in quite some time and nobody else has seemed to have any problems, either.

'Other' classes are not able to reference the world unless you pass the world (or an actor that is in that world) into it. This can be done when you create an object of that class (in the constructor of that class) or when calling a method on an object of that class.

Please refer to the Greenfoot class API. The method is 'start' (not 'run'). 'a' and 'd' is left and right; 'space' is shoot.

I think this is pretty clear. Current results for favorite game style: 27 RPG 17 Platformer 16 Strategy 16 Shooter 12 Action 5 Fighting 5 Traditional 4 Simulation 3 Racing 0 Education

Does anyone else see the walls of the maze having a red tint in their color and having vertical lines between each instance? (the walls are supposed to be blue and no lines should appear between them -- as they were before uploading)

@Builderboy2005, I believe the framerate increases as the game progresses, speeding up the objects that you have to avoid, making it harder as time goes on.

@DonaldDuck, I know that you are not allowed to add instance or class fields to the Greep class, unless they are final fields. However, they do not explicitly disallow local fields (those whose scope ends when the method they are in has completed its execution).
