I know, I know, I was supposed to make Jazz in Action. But when I was talking about it I didn't have good program for making 2D games. You see, even then I wanted to make JVS more than JiA - but I was unable to do it. Now, when I have full version of The Games Factory (in Polish language even) my dream came true! You can see the first screen right here:

I hope it opens for you and you'll like the game idea!
