In a JQuery game someone done a project for me, but there is one problem. When drag a block, then refresh the page your character can go through the block.
Try it here :
[url removed, login to view]
This should take 5 minutes for anyone with JQuery experience, it's simple but I don't have much experience. I do not want you to change much code or add much code, just see what the problem is. It was working yesterday, so could be something as simple as missing a ';'.
