Yea I remember playing it back in the day. It was called "Blockout" - http://en.wikipedia.org/wiki/Blockout

It was indeed. A friend of mine liked it enough to replicate as a Java applet - http://brokout.org/

My site, but his app. Oh and for amusement value note the specs that it was tested against...

I guess it's necessary in order to see the blocks at the bottom, but the ultra-wide field of view makes it hard to tell visually when the blocks have reached the top two levels.

The game you're thinking of for DOS was called 'Block-out'. I used to play it on my Dad's computer all the time when I was little. =)

There are two blockout clones for Android: one named Blockx, and the other named Blockout. I haven't tried either, but the spirit of the game is apparently still alive.
