Looks like we had a pretty similar idea haha!
I love the Title Screen Graphic and obviously the scaling mechanic. Tying it to a bar is a good idea. I feel like the game could use a little faster pace, by making the pieces descend quicker. Also, it would be nice to able to hold down A and D. Lastly, I think changing the scale shouldn't move the piece all the way back up.
Obviously these are just suggestions to make this game created in such a short time even better!
