The bone throwing mechanic made this game for me. I love the "save your dog" theme too.
A super fun concept. Worth expanding on, I think. The art work of the pest being only 3 pixels big really let my imagination run wild. Love it.
Edit: I actually went back and played it again. Very fun. I think there's an issue with your text being inside the game window, though. And not sure if it's technically 64x64 since it's not a square aspect ratio? But a fun mechanic for sure!
