Yep, and I thought about it, I'll just post my current file, just to see how it works for others. There's no actual game yet, but all the UI stuff is done.
Edit:
Forgot the controls
On - exit the program from any location
2nd - A button
ALPHA - B button
I also plan to make the intro animated, if anyone can give me a good gif animation for a good intro page, link it to me. Hopefully it has something to do with the current one (hint hint) for the parts of the game.
Double edit:
One last thing, I don't know how to make tetris.

(will take too long to read through or think about it) Anyone have some source code I can use?
