I understand that the game is still in development, so I hope my comment helps to provide some feedback on glitches.
Currently, I have no idea what the petting mechanic does. My blue bar fills up but what is the point of filling that up? It's also confusing for the green bar to be the "food health" bar because eating reduces it, while petting increases the blue bar. I think the green bar should move oppositely.
The frog also wanted me to kill him, and I did, but using the knife on him made him tell me to stop, so I had no idea what he wanted. After killing him, he also died of hunger, then he told me that he hasn't seen me in years. I was so confused, I think multiple endings happened at the same time.
I think the game can be fun, but there has to be some tweaks. I think the frog should talk automatically rather than through a button. This provides the player with visual confirmation that progress has been made; that there's a consequence to their actions.
