Mystic Messenger Related: How long would it take to fully complete Mystic Messenger WITHOUT the use of hourglasses?

[May]

By fully complete, I mean /all/ the endings included. How many days would it take to get through each ending?

[house-special curry]

11 days x 5 characters = 55 days for Normal Ends
11 x 5 = 55 days for Happy Ends
?? The other ends. There are at least 2 bad ends each for all 5 characters, so 10 ends, but they all take place at different points with the various routes

So, 110 days plus ?? days for the other bad ends. I'd guesstimate around a year or less?

That said, even free players get free hourglasses from time to time, and it makes much more sense to save at branching points (like Day 5) and reload later for 5hg to get the other ends. Much quicker. Probably 8 days per route for all the bad ends, which would be 40 days total.

If you save at the same point, Day 5, you could also get each character's Normal or Happy Ends and save yourself another 4 days per route. That would be 20 saved days.

So, by saving and loading only on day 5 per character's route, using only earned hourglasses from free play, that'd be...

130 days?

That said, there are probably even more optimal ways of playing it for less days, but. Too lazy to calculate that by looking up all the branching points of everyone's character routes.
