"Unfortunately, GreenfootImage is a bit slow, and i need to figure out how to write to the awt image directly XD" GreenfootImage.getAwtImage() ..?

Thought - when the spider is drawing the lines out from the centre to the edges, how does it travel vertically upwards without having anything to hold onto?

Also: If you're stuck with why nothing's happening, then export the scenario and check "include source code", that way people can look at the source and see / tell you what the problem is :-)

I wouldn't worry about counting it out into seconds exactly, most of the time for game timers you want something based on pretend time anyway. One thing you might want to look at, I seem to be able to go forward, turn right and shoot at the same time, but not do the same thing whilst turning left?

Nice simple game - you might want to change the images though so they go forwards and not sideways! You should just be able to do this by overriding the addedToWorld method in your rocket / car classes, calling the getImage() method to get a reference to the image on the actor, then calling the rotate method on that :-)

Nice start on this! Lots more that could be implemented if you're interested in improving it - the most obvious one as stated above would be some sort of lives / dying in place so you die when you get hit or the wasps reach the bottom (at the moment they seem to keep on going and going!) Then there's scores, shields, bullets - imagination is your limit with this one ;-)
