Such cute art! I am impressed you managed to make a platformer game actually feel cozy! (I find that this genre is usually either competitive, or intentional ragebait :D so it was a welcome change). I enjoyed the small details as well, like the way the light from the lanterns moves.
Minor things:
Since the first prompt I saw was "this is your home", I instantly pressed space, because I wanted to interact with it. Then, the level changed, and I thought I did something wrong, so I restarted the game. Only when I restarted did I see the text (further away) explaining the "if you want to sleep, enter your house" mechanic. Maybe you could bring it a little closer to the house? Or maybe I am the only one who did this :D
It would be nice to have an indicator somewhere that tells the player how many friends they managed to help, and how many more need help in the level.
As mentioned below by others, some music would add to the charm.
