23:18 Just to let you know table coral not only grows in the lily pads but also in the moderately deep twisty bridges, the biome neighboring the starting shallow twisty bridges, It's the one with the Sea Truck fragments, the single compartment abandoned base, and the brute sharks. In the moderately deep twisty bridges it is red instead of green but it still works exactly the same. You should go there instead because It's much closer.
7:20, the reason why the high capacity oxygen tank contains 90 seconds of oxygen yet your actual oxygen is 135 seconds is because the 90 seconds totaled with the 45 seconds the player can hold their breath for totals up to 135.
Also at 10:16 I do have to say that you don't have to build solar panels on the blue part, it just has to be on the roof, you just weren't close enough at first because they changed how base module outlines move in a 3d space from Subnautica to Below Zero.
