Tetris infoidiomas

Controls:
top - turn
down - move down
left - move left
right - move right
space bar - drop
N - new game
R - reset

Rules:
1) Speed = 80+700/miliseconds, less value means faster drop speed
2) If completed on the current level = 10+level*2
3) After finishing, speed increases in 1000*level*deleted lines
4) Every drop increases 5 points (pressing space bar counts as multiple drops)
