What a lovely game! Simple but satisfying, and the bug hybrids are a nice extra touch. Chill music and SFX that adds to the atmosphere and isn't annoying or out of place. And the moth designs are beautiful--it was fun to hatch a new one and see what it looked like!
I guess the only critique I can think of is that it wasn't clear if clicking on the eggs was making them hatch any faster? I think clicking on the worms was helping them turn into moths faster, but I might have been making things up.
The Windows version took a little while to shut down which might mean there's some significant memory overhead there as well. It shut down fine after a few seconds though.
Great work all around!
