I’ve still got a couple of hundred bytes to spare, so I need some ideas, and possible improvements!

Comments please! 
Addictive.
Shouldn’t you be able to rotate the | piece when it’s up against the walls?
Well, I have to say it’s quite a good adaptation, and the fact that you got most of the original music in there in 4k is really great. I played until about 800 points then I quit. Can’t think of much more you could add in, other than many multiple players on the same keyboard or something like that.
Well, this is an accurate remake, and a good first entry to the contest. About some ideas and improvements :
- this is quite obvious, but why not adding some colors to the falling bricks ?
- the game may propose to start at different difficulty levels.
Great remake!
+1 for colors.
Thanks for the comments.
I’ve added coloured blocks, and changed the colour style a bit.
There’s also a mute for the music if you find it a bit too repetitive.
