Fun little game! I'm a bit of a sucker for these sort of management games.
Made it to 2nd or 3rd on the leaderboard, but alas didn't quite make it to the top;
It's a solid idea, but could do with a bit of quality of life like sorting the adventurer ranks; and mechanics to make deciding on adventurers to send a little more interesting. Understandable though, for only a week (I got much less done haha)! The gameplay loop does get a little tedious as-is, as there are periods where I'll settle too long into the rhythm of just formulaically picking the same party compositions for the given quest rank just over and over. I did quite like the option to double-or-nothing for a higher reward though, fits the theme well and becomes more exciting and meaningful the closer you get to day 50.
Nice work!
