Blocks from Hell

If you hadn't guessed, the gameplay itself is far from new. It is, in fact, almost identical to that of many others: move and rotate 4-block pieces while they fall, and try to arrange them to fill horizontal lines.
The keyboard control is simple - I suggest using the numeric keypad to play. Move the piece left and right with the arrow keys (or 4 and 6 on the keypad), rotate with 5 and 8, down (or 2) to speed its fall, and space to drop it immediately. Pressing P will toggle the pause mode, and pressing S will toggle the sound when lines are cleared. Escape will abort the current game, and F10 will exit the program immediately from any point.
The scoring is also pretty easy - you get 6 points for each piece you play, plus a bonus for the level number you're on, plus a bonus for each line that it fell while being dropped with the space bar, plus a bonus if you don't use the "Next Piece" option. When you clear lines, the scoring is as follows:
1 line : 100 points
2 lines : 200 points
3 lines : 400 points
4 lines : 800 points
