Thank you for trying it out! Sorry about the text issue in the tutorial scene, somehow the text wrapping became disabled during a previous UI bugfix...
At the beginning of each turn, every person's resources and needs are randomized. If a person is not sending their resources to another person, they apply it to their own needs. If any category of need is unmet, the exclamation point appears (and they'll lose health at the end of the turn).
There isn't any game over criteria, the game ends after 20 turns and you get a score. The win/loss condition is kinda just whether or not you managed to keep everyone's health above 0 for 20 turns.
