Okay, the game is uploaded. It's not great. I had some other things come up so I was only able to spend a couple days worth of time on it total. I had to cut the mechanics where you work against your reflection before you work together, so the connection to the theme isn't as clear as I wanted. Still, let me know if you find any bugs.

Version difference and performance note: I recommend playing version 2 of this game. If you have the option, Pygame 1.9.6 will get you better performance than Pygame 2.1.2. On the last day when I went to test it with 2.1.2 I found a severe performance degradation. Pygame 1.9.6 is apparently much more efficient at drawing enormous polygons with pygame.draw.polygon, which is used to draw the mask for the reflection effect in the game. If you want to test whether your version of pygame is affected, try out the following code. It will either take a fraction of a second, or several seconds:

import pygame
screen = pygame.display.set_mode((500, 500))
pygame.draw.polygon(screen, (0,0,0), [(0,0), (0,100000), (100000,0)])

Because of this, version 1 is unplayably slow with Pygame 2.1.2. During the upload period, I implemented a workaround to reduce the size of the polygons drawn, which version 2 includes. Version 2 is still slower with Pygame 2.1.2 than Pygame 1.9.6, but should be playable. You'll still see bad framerates, but it should be more like 10fps than 0.1fps. Let me know if you still have any issue. Thanks!
