I really like all the elements that come together here. The art style is great, and the faded/bright rooms are effective for indicating what I need to do.
I definitely couldn't parse what rooms bugs wanted to go to beyond "sunny/dark - up or down," but that wasn't a big deal. I do have two critiques about hunger:
One, I think clicking on the bug (or even the room) itself should also work for bringing up the food menu, not just clicking on the tiny hunger bubble. It seems like the game is trying to test your multitasking skills, not your precision click skills, but maybe you meant for both.
Two, there's no easy way to put this - I'm finding the sound effect you used for hunger to be deeply unnerving, and it's the main reason I stopped playing lol. I know it's just a funny sound effect and I may be the outlier, but I feel like it works against the charming vibe the game is otherwise cultivating. Some gentle music would also go a very long way.
Nonetheless, this definitely has potential, and works well! Great job!
