The Timeframe of the Main Plot
This is not exactly missable or hidden, and the math is really easy to do, but for everyone who is interested:
The game starts off with the BLADE Tower display at 60% and it is stated in the beginning that two months have passed since the White Whale crashlanded, this means:
2 months (i.e. 60 days) = 40% energy loss
With the rule of three we can determine that
1% = 60/40 = 1.5 days
or, the other way around: 1 day = 0,6667 %(rounded up) energy loss
The last percentage we see is in Ch.11 and 12 and shows 5% left which means that the value fell by 55% over the course of the main plot. This means 1.5 days x 55 = 82, 5 days.
Things to note:
I approximated 1 month = 30 days bc it’s easier to work with a fixed value.
This assumes that the drop of energy is proportional and there isn’t some sort of energy saving mechanism that kicks in once the percentage drops beneath a certain value (as is the case with smartphones for example). (As the game never mentions anything of the sort I don’t think there is, really. Like, how would that thing even save energy - certainly not by weakening the barriers surrounding it or shutting down the super computer that holds everyone’s consciousness)
