Columns for 2 players

Hi. I had this code on my hard drive for ages now, and never finished it, so I submit it as it is. I just wanted to experiment with 2 simultaneous players gaming, and I don't fancy finishing it (no point, there are plenty of similar games around plus I'm not going to submit a finished game source code that some &$%£"$£ will probably nick and release it as a shareware for easy bucks). The engine comes from my Tetris clone "SliTris" (game rules had to be tweaked of course, and that wasn't as easy as I expected :(), i.e. sprites with backbuffer for smooth gameplay. The main form again doesn't contain one single control, no text box, no image box, no timer... all is done via APIs for optimised and flicker free gameplay. Features original graphics shamelessly stole from Sega's original game :) Hope you'll like it and maybe finish it. Note: I had to remove all skins but the main one to keep size down :(
