Unicat explains almost everything. The hunger and happiness mechanics work by clicking on the bell, fish, ball, and bed. The fish raises hunger, the bell raises happiness, The ball will raise happiness but will decrease energy, and the bed will raise energy. The Health icon is NOT fully implemented and will do nothing. Have Fun!
This game is in its Omega stage, so sorry if it sucks. I like it anyway and will add to it, I promise. (If you comment below, I'll know what to add!) IMPORTANT NOTICE: This project is ON HIATUS so I can make new stuff. I'll come back to it eventually, I guess.
