Super cute little narrative experience. The visuals really work well to deliver the appropriate tone and while short, it does pack a nice thematic punch! I personally am a big fan of the art direction at work here.
In terms of where to go from here - I could see you perhaps fleshing out the thematic core via a branching pathway (playing with - say - the player avoiding death in interesting ways). It would also make for a stronger replayability factor and more opportunities for players to catch some of the smaller details sprinkled throughout the title.
Overall amazing job!!
