Try to survive as long as possible. What you eat determines the results - eat too much sugar and you lose, eat too little and your character could starve if the hunger drops to zero.
Different food brings different amounts of sugar spike and hunger levels. Same as in real world, sugar spike takes more time to drop than it takes for a human to get hungry again.
Healthy drinks can make you run faster for a short amount of time, unhealthy drinks can make you slower.
Enjoy the game and best of luck with your high score!
Feaster is a hypercasual game that will make you think about what you eat!
