The No Time to Lose achievement is pretty tricky to get. You'll basically have to be on point every step of the way as there is little leeway. I do recommend timing yourself instead of relying on the playtime displayed on Steam Overlay and either writing down the solutions or have them up on another screen.

The timer starts sometime between the black screen and when the visuals pop up and ends after the last cutscene where the achievement pops up on the credit screen.

In addition with including solutions and shortcuts, I'll include the times I got. I ended each lap time when the lock (autosave icon) popped up and stopped the timer when the achievement popped up.

Check out Hellinouille's guide as well! I reference it a bit and it'll be helpful if you want to see solution screenshots.

For Chapter 1, I basically did the RGB machine first, the clock second, and then the rotate puzzle last.

• RBG solution: R = 220 G = 50 B = 35
  
• Clock: Yellow = IX B= VII. You can click the other button while you wait for the first one to reset to quickly solve this puzzle.

You can skip all the puzzles and just input all the numbers in the phone

• 5518
  
• 4036
  
• 1926

Make sure to do both puzzles per time and use the doors as a shortcut.
The first dawn puzzle is going to make or break your run. If you spend too much time retrying here you'll be too late. I used 62, 100, 31, 58 solution. There is a bit of leeway here, but the first number can't be more than 69. I solved it in three tries.

Just walk right and then immediately go left once you see the light.

After you turn on the music box, just walk left. You'll pass the puzzle table again before the cradle, but you won't have a high chance of the cradle cutscene not activating this way.

I did the puzzles on the left then the puzzles on the right.

Where you need to rotate/flip the symbols, you can save time by simply:
1. Rotate once -> insert
2. Flip once -> insert
3. Rotate once -> insert
4. Flip once -> insert

(Just remember for the the first two, the red boxes will be facing each other, with the third one facing up and the last one facing down.)

For the multiple rotating circle puzzles, just do one at a time and just try to stop it right when it turns red.

To open the door, rotate the wheel:

• Right x 3
  
• Left
  
• Right
  
• Left x 3
  
• Right

You can skip the rotating constellation puzzle on the far right and instead go straight to the tree branch puzzle.


For the television one, I tried to copy a screenshot of it already solved as close as I can and adjust it when needed. The more you do it, the better you get at it. You do not have to drag out the panel that pops out.

When you have to insert the 3 constellations in order, you can do them out of order as long as you have the right space selected (ie you can insert Capricorn and Leo at the same time and then rotate to insert Libra in the middle)

Just walk to the right and don't forget about the piano segment. The cutscenes here take about 3 minutes.

If you're under 22 minutes when the last cutscene ends, the achievement will pop up!

Hopefully this helped!
