WOW, I love the feedback I get here. MUCH better than newgrounds! I'll have to make a second version of the game with all these fixes. However, I did try to fix the falling block thing, when you make a horizontal group, the ones above fall, but the vertical groups were stubborn and I couldn't get that to work out.
