Cool game! The art, music, writing are all great! The only things I'd suggest is perhaps make it more obvious that you're supposed to talk to the cat (was stuck on that for a while) and it'd be really nice to be able to advance dialog faster. Even when on the click to advance mode, there's this slightly long delay before letting the player advance dialog that's a bit annoying for those of us that read fast...
Also, I feel bad for grandma :(
