I better got on with some science then!

I have to get a science GCSE from a couple of years ago done, sorting out the questions into ones I can do, one that are OK and ones that I'm not sure of. For the latter group I have to go through them again with the revision guide to find the answer, I just want to LIVE!

On a side note - if anyone out there uses Game Maker, how does one make an up and down moving platform, I sort of did it but the player object got stuck and I decided to for get the idea. Also if any of you have idea for levels I would appreciate them. It is a platform game based in the vaults of Habbo Hotel. The game is called Tobbin - Habbo Thief, after something by brother said after seeing Wayne's World - "In France she would be called 'le renard' and would be hunted with only her cunning to protect her" - But he changed she for he and le renard for tobbin to describe his friend Toby.
