The TAS works is that by rapidly pressing left and right it tricks the game into thinking it's more further to the left than it is, so the invisible walls are now pushed more back, giving the player an opportunity to go beyond the restricted space. Evidence: there are variables which will change depending on the main sprite's co-ordinates. OLD VERSION: -------------------------------------------------------------------------Nevertheless, it is a TAS. There are only 5 possibilities: 1. It doesn't work, you have to click the green flag again. (unsuccessful) 2. It does clip but your depth doesn't change. (semi-successful) 3. It does clip but your depth changes. (successful) 4. It digs once and nothing else happens next. (unsuccessful) 5. When digging by luck you fell down as there were no bricks for support. The game counts that as a successful attempt but it really isn't.
