The art in this one is really great! Using one location for a majority of the game is a really smart way to save on development time when you're hand-drawing so much. Of course,  it also works well with the main allegory of the game being the protagonist's inability to make any progress with their mother. Starting over so often was a little frustrating for me personally, but I think that's just how my brain operates when playing games like this.

I mostly liked the approach you took with the writing as well. It shows a very specific type of abuse (and a very specific reaction to it) that's hard to capture in art. It's a lot easier to just show overt violence as shorthand for child abuse, so I respect the depiction of the much more common slow wearing down of a child's confidence and wellbeing. Like I said, the symbolism of the frozen setting and the gameplay mechanics are great for this subject. My only criticism is that the exposition towards the end feels a little direct in comparison. The mother's antagonism in particular seems to condense down years' worth of verbal abuse into a very short speech, so we don't really get to see the sense of love or familiarity that makes their relationship so complicated.

This is really only noticeable because the rest of the storytelling is handled so well just through basic character interactions and imagery, though. You've already got great visuals and interactions throughout the game for most of what you're telling the player, so I think they could do a bit more heavy lifting than you think. (I also get that planning out a story that touches on such a complex issue, especially one that has to condense such a large span of time into such a short timeframe, is just super difficult for a jam entry.) I'm very into what you've made here regardless, and I hope you continue to develop games and tell stories like this one.
