The art, nice, good colors.
I liked the story, mostly with the whole thing about the grandma and their friend was nice.
Gameplay was good, nice concpet of different outfit wearing done well.
I wish there was some more reaction for characters and outfits so the text could be a bit less "BAD OUTFIT! BAD OUTFIT! Oh I like this one have some sweets!", but I won't really get on you too much for it, given it's a game jam and all.
Also I dear add, on a programming level, it felt like was held together with old string.. No offence to your programmer, just could use a bit more time in the oven then how long you were given to make it.
Case in point bug happened to me once or twice where I went to house and the people who came out just.. Didn't say anything.. I think it had something to do with the outfit I was wearing because when I left and I changed they worked fine again.
So all together, not bad, I like it. But would be better nice with a little polish. Well done.
