The 2 'L shaped' figures..
...have the same color, that's kind of confusing. The basics are good, but you need to spice everything up a little.
You need some sound, better graphics, probly a background (instead of the grey) and you need to make the lines disappear faster when you complete a row.. if you do this you will get a much better score
Its kind of boring after 45 seconds.
Its just not addictive like the actual tetris is.
Add Some Music and Some Better/More creative Backgrounds and scoring tables and maybe this could make front page. As the dude that came b4 me said, I will never play this again, but with some cool music and stuff, this game could be greatly improved
