Scratch

By Monday (the 19th) I need to have a completed game in scratch for my IT project; I've done part of it, but am completely clueless on how to finish it - I don't want anything special, stuff I can do instantly on other game makers, but Scratch's interface has completely stumped me and I've no idea how to get what I want.

Below is a detailed description of what I wanted in the game, (which we had to write up beforehand.)

On the first level you are placed into a square world with ledges on the edges of it. In the centre are 10 black motionless circles. Your character, (a star,) is moved by wasd. When you move into the centre area you move at double normal speed, (2x) and also bounce wildly off of everything you hit. (Move at 3x the speed for 2 seconds after impact.) If you hit a black circle, it changes colour to white, and if you hit a white circle it changes to black. The circles are solid, and so cannot be moved through. You also bounce off the ledges at 3x. To 'jump' onto the ledges you must hold down the spacebar whilst going towards it; you move slower on the ledges (normal speed) and do not bounce when hitting anything. When all of the black circles are white, you go up a level. There is a time limit in which you must achieve each level or you will be sent back to the start of the level you are on. On the subsequent levels the game becomes much more difficult and different.

Anyway, I don't care about the time limit, or even going up a level - just getting ONE level would be enough.

This is what I have so far; http://tinypic.com/r/330rzpx/5

I will be watching this thread throughout today, so if anyone could help me at all, I would be SO grateful, however small the advice. Thankyou for reading though.
