Required playthroughs: 2+. Theoretically one enough, with some chapter select replays, but it is doubtful anyone would do the speedrun achievement during the first playthrough.
100% difficulty: 4/10. Speedrun is quite doable already on the second playthrough and just need to be extra careful while attempting the “steady as you go”, which is not that hard either.
Chapter select available?: Yes, if you missed anything, you can return to that point via “load”. Only speedrun required starting with a new game but starting a new game don’t reset stats so you don’t need to farm “travel distance” achievements before attempting the speedrun.
100% completion time: 10-12h, while I guess noone going to do the speedrun achievement on first walkthrough because even watching vids before or during that walkthrough, you will just get some delay and you would run out of time.

Speedrun Walkthrough Video aka “At a rate of knots”
Complete the journey in less than 210 minutesYou will have 3hours and 30minutes to finish a game, which isn’t hard on a second playthrough. I still had time to waste in this run, collected all containers and made the flower to reach its full potential.
Distance traveling achievements
Travel 1000m using the Boost ModuleEventually you will get the boost module upgrade. While your ship boosted it will travel faster. Essential for speedrun achievement but I also traveled 1000m with it during my first playthrough so I believe this could be literally a storyline achievement. If you unsure how to use the boost then you can check one preparation and useage at 2:02:36-2:03:20 on the video but here is also an explanation:
1. Start the burner and heat it up, and keep the green marked area in the blue fields.
2. While keeping the green marked area in the blue fields don’t forget to cool down the yellow marked area with your water hose.
3. Once the button at the orange marked area becomes active, then use it.
Travel 10000m aboard the vessel while submerged
10km while submerged is quite lot and this was my last achievement, together with the perfection achievement. Don’t focus on getting this early, you can get it later, you might also get it while trying for “steady as you go” achievement. If you still need it once done with everything else, then load checkpoint #30, you can travel there submerged without obstacled for a quite long time. Repeat if required.
Flower related achievements
You can get a flower at the beginning of the game. If you missed it, you can return to it and pick it up with loading the chapter marked with number #1, so you need to load up the very first checkpoint. Eventually you will get to a spot and you need to pick up the flower and carry it to your ship:
Just store the flower first on your ship and continue your journey, you will have 2 options to deal with it. I suggest to do option 1 in your speedrun and do option 2 in your first, regular playthrough, as all achievements in options 2 will take more time.
Burn the flower
Once you unlock the steam engine for your ship, then justuse the flower as a fuel and burn it.
Plant the flower in the vessel
Just keep the flower until you get another ship upgrade and you can plant the flower at the following part of your ship: (HOW?: Just drop the flower at the marked location)
If still unsure about how it goes, you can watch the planting on the video at 48:00.
I’m Rooting For You!
Water the flower
Beauty in Disaster
Grow the flower to its full potential
Now water the planet as you can see on the picture to get I’m Rooting For You! and periodically return and water the plant again and again during your journey to get Beauty in Disaster. Also make sure the roof above the flower is open (blue marked area on the next picture and the blue button is next to it) and travel on the water as much as you can instead going submarine mode even when it is not necessary. The flower reaching its full potential on the video too, it is at ~2:00:25.
Other Missable Achievements
Burn 100 fuelBurn 100 fuels. Sounds annoying right? Because you won’t burn that many during 2 playthroughs, not even half of them. Just load a checkpoint where you had MANY fuels and add them to burner. Nope, you don’t need to wait until they are burned, you can add fuels to it even if its full and the counter already goes up. Reload that checkpoint until achievement earned.
King of the World!
Stand at the prow of the vessel while travelling at full speed
Be at the marked location while the steam engine(burner) working and the sails also got maximum power. The boost not required for this achievement:
Push all the buoys out of the way
Push away all the buoys with your ship. Originally i would think this achievement is a storyline achievement, but actually you could skip some while going underwater. So don’t do that, because you need to do it in one run:-)
Running a Tight Ship
Successfully repair key parts of the vessel 10 times
You will find some kind of oil can with 6 charges (when full) and you need to repair your ship 10 times total. If you having issues to get this (then you playing the game perfectly:-D) then don’t cool down the engine while the burner is active or don’t lower the sails when you passing a bridge. You can eventually keep the damage and reload the checkpoint to get the total 10 if neccessary.
Running on Fumes
Burned the last item onboard
Run out of fuels completly on your ship. Again, if not earned during your regular gameplay, just load a checkpoint and add all of your item to the burner.
Salvage the contents of 6 containers in a single journey
Collect 6 containers with the hook of your ship. 2 containers need to be collected to progress in the game, the other ones you could find at the bouys, on the groundfloor of the ocean/sea. You need to collect 6 in a single run, but there are at least 7 you can find in one run. Locations of those 7 on the walkthrough video:
- 48:25 – 48:40 (unmissable)
- 52:48 – 53:45
- 1:16:35 – 1:20:00 (unmissable)
- 1:40:05 – 1:45:30 (this was a trickier and i wasted like 4 extra minutes here)
- 1:55:40 – 1:56:25
- 2:32:50 – 2:34:15
- 2:59:23 – 3:00:00
Steady as you Go
Navigate the underwater caves near the waterfall without bumping into them
You need to pass the area you load with the chapter select #51 checkpoint.
This is the area where you need to start and need to avoid bumping to any walls:
And you should get the achievement once you reach the balloon.
The affected area on the video: 3:00:53 – 3:04:20
Attain all other achievementsThis achievement unlocks as last, together with your other, last missing achievement. You can start new game anytime. That not affecting your progress toward this achievement as your stats don’t reset with a new game.
