Ultra Tetris

 Encontre una hidden feature de este juego hecho en TBXL

After checking the Turbo BASIC XL source code, I discovered a hidden feature that can be activated while the game is paused.

- Press ESC to pause the game.
- Type IPC-CLEAR.
- Push the joystick UP.
- Press ESC again to resume the game.

When the game resumes, all of the pieces should be removed.
