Great work! And it's cool to see an entry with an Android version, it was nice to play it on my phone.
The Earth and Moon expressions are really cute, and I liked the talking animation in the intro :D
The gameplay works well, though it's really challenging, but I did manage to reach 27 as high score! It takes some luck to have enough ready-to-throw garbage near where the Moon is, but it's still fairly well balanced.
And the music and sfx are very fitting too :)
