Great concept, obviously it got a bit repetitive once I figured out the controls, but I can see the hunger/thirst mechanic being used in a larger game.
the fish catching button text was a bit misleading because I thought I could not catch a fish, but it only says that because the button is on cooldown. Maybe you can change it to something like "A fish was caught" so the player knows the action was successful.
Overall, a nice game 5/5!
