Thank you for your attention to our game. Of course, everything you see on the screen is fully implemented, and you can influence each status of each character. Unfortunately, we did not have enough time to implement an in-game tutorial, so I am attaching it here.
In order to feed or water a character, you need to use the corresponding buttons for the characters. The left button is water, the right is food. Statuses are not updated immediately, but the next day. The opacity of the pressed button means that the next day the character will improve the corresponding status, you can also change your mind and press the button again so that you do not spend resources and the character does not replenish thirst or hunger
