This was neat! I like the little intro scene, and you managed to put a clear narrative into a really short game. Great work!
I think the easiest thing you could do to improve the game would be to add audio. I can usually put together sfx for the 3-5 most important actions in less than 20 minutes. You can find a lot of decent stuff on freesound. And the quality of the audio matters a lot less than just having something there, the main thing is giving the player feedback on their actions.
The art is gorgeous. I really like it, I’m really happy to see someone putting in this much effort on the art of a jam game.
