The dimensions of this scenario are too big for my monitor which is 1920x1080 pixels, all I can see is two yellow circles and some blue shapes. What am I supposed to do in this scenario?

"It's hard to see what's happening if I can only see a fraction of the scenario." (<-- quote from two posts/comments ago). "The dimensions of this scenario are too big for my monitor which is 1920x1080 pixels, all I can see is two yellow circles and some blue shapes." (<-- quote from three posts/comments ago). Basically the world is too big to see on my monitor which isn't so small, so I can only see a part of the world. The part that I can see is some blue (which you mentioned is a house), and some yellow circles.

But you said "nothing is happening. you walk around and don't bump into the house." and "and you use wasd to move". When I press 'w', 'a', 's', or 'd' I don't see anything happening, so to me your scenario looks like a colorful picture. (I'm not saying that's all it is, if you got it to walk around but not bump into houses that's good but it LOOKS LIKE a colorful picture.)

When I click on the link that says "Visit the web page for this scenario" the following message pops up (http://www.greenfoot.org/scenarios/nemosblog.weebly.com): "The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved (the Greenfoot site was signifcantly altered in late 2011, which moved/removed many pages). Try going to the main Greenfoot site instead." Just a side note.
