This was an interesting take on the theme, literally. We are actually shooting the moon. I like it. I was also able to make a shield shoot combo, which was cool.
One point I think could make the game easier, is to have more (white) space on the top and bottom part of the game. We don’t see enemies that come from above/below when we are on the top/bottom part of the screen.
It is difficult to do everything within a month. I think you have done a good job with the current time limit. Cheers~
