Clean-Up coding and fix little problems in Tetris Game

I've got a nice little (Visual Basic) Tetris game working with Active-X. The coding of this program is a little bit messy, so I need someone to clean it up and make it work better. There is also a small problem which occurs sometimes: When you make a line it has to dissapear, sometimes not all the blocks will dissapear and one or two blocks will stay behind. They are only visible to the user, but in the game they don't exist. So you can't make a line with one of those blocks which are left behind because for the game they don't exist anymore (but they are visible within the game for the player)... ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
