@dan11, how would you go about fine tuning the game in this situation? (not that I need to know, myself -- but for others, and for K_wow). To clarify: when simplified by moving one pixel at a time, you can move left, right, up, or down, at a speed of one pixel per move; but, when moving diagonally, you cannot. Then, you must move by multiples of the square root of 2. That is the distance between two diagonally adjacent pixels.

@vakz2013, play the game while logged in. At the end,, the high scores will show with button across the bottom of the window to view the different classes or start a new game.

If you want others to be able to have access, you must check the 'Publish source code' checkbox every time you upload/update the scenario.

If and when you manually add actors into your world, please 'Save the world' before uploading the scenario. All I see above is sand, which is not 'cool'.

Or you could download my Image Transparency Addeer/Remover scenario. Just run, load and save. It will automatically reduce it to minimum image size. It is located here: http://www.greenfoot.org/scenarios/7423
