Controls (as in feeding the dog) weren't really intuitive, I had to read how to do it in your description which shouldn't be necessary for this depth of gameplay. Speaking of which, black text on dark blue background is really tough to read.
The day cycle sure was nice, even if it had no impact on the game. Besides that, it obviously didn't keep me playing for too long.
Some music is really necessary for a cozy-style game as this.
