The following are tips for completing the game in under five hours and never dying:
1-) There is no way to view your in-game time. Use a stopwatch to keep track.
2-) Restarting checkpoints does not count as a death. Make use of this when you are about to die, miss a jump, or fall into the abyss.
3-) Getting eaten by Trico does not count as a death. He will eat you in the antenna rooms, which is part of the story and results in a cutscene.
4-) Back up your saved game (using a USB device or PS+ Cloud) whenever you have completed a section quickly. If you were slow, reload that save to try again. Go to PS4 Settings – Application Saved Data Management to backup and restore save games.
5-) Sometimes Trico glitches out and does not do what he is supposed to. The controls can also be difficult at some points. These are common problems and the biggest challenge in completing the game in five hours. You sometimes have to get lucky that Trico listens to your commands. If you are stuck for too long, reload your last backup save.
6-) When pausing the game, it is recommended to dashboard out to the XMB (press PS button after pausing). This is probably not needed, but it is the safest option since it will completely stop the game.
7-) There is no chapter select. This means the only way to practice is by reloading your backed-up save. Then, play the next section until you are satisfied with your speed. Reload the save from the USB/PS+ to practice the section again.
8.) The game keeps counting the time when you die (and does not reset the timer to last checkpoint). Dying can cost a lot of time if you have to repeat long sections. Always reload the backup save when you die.
9-) Pressing R1 + Triangle tells Trico to jump up. Face in the direction you want him to jump to. This is the command you will need the most. It only works after unlocking this skill a while after the first antenna.
