Great work, for 2 hours! I love whack-a-mole (I actually have a huuuuge old 'Whack-a-gator" machine in my basement, it doesn't work though lol).
This is a good start. Only real criticism would be the music's super loud, and the top left (back) hole/flag is hard to click on, you have to go out into space away from it for the click to register (at least for me!)
Good job/good luck to you
