What about high scores? It would be fantastic if you could give your high score and every time you pass a specific marker its saved somewhere on the net where other's could see it. For those who are really good they could compete.

When you right click to change some settings this should automatically pause the game, let you make your setting changes and the resume when you exit the settings. Rigth now if you right click and play with the settings the game is still going on in the background. This is a no no.

Its great man really really good job i wanted something like this from a long time i like tetris too much Thanks A Lot Keep going Thankssssssssssssss

I agree, The arrow keys would be much easier to use and a more logical choice. I would like the ability to scale this from its current size to 2-3x its size. It's currently too small especially when playing and baloons are constantly popping up. These baloons are very annoying.

Instead of dropping when you press the K key, can you please speed up the decent like tetris originally does. It's tedious waiting for blocks to fall when you should easily be able to speed it up, flip and place.

USE THE ARROW KEYS, THAT'S WHAT THEY ARE FOR.

You can keep the "jkl" controls, but at least ADD THE ARROW KEYS!

Would be a 4/4 if it used the arrow keys! common sense people!
