There is only one possible way to to beat the game (at current state) so I am gonna focus on details.

'Shift' + 'A', 'D' or any narrow keys make you walk faster, 'Space' to skip animations (some of them are unskippable),

Keyboard buttons we use on the run:

1. X --> S --> O
2. First signal on 300
3. Shift + S + LMB --> Scroll Down
4. Nothing need memorizing untill first puzzle, look at screen below
5. Second puzzle: BHUYTG --> Shift --> Scroll down
6. Mash B, then hold O, Shift + S, X
7. Last signal: one mark to the left from 450
