Hi Nick, I added some comments and stuff while you were teaching.
Hope you have less stressful sessions than I did!

I had a really simple game idea for the two
students, it was where you would dodge
a bunch of pygame rectangles being spawned
and you have to dodge the rectangles being spawned.

There are a bunch of example code within pygame itself
https://github.com/pygame/pygame/tree/main/examples

If you need help with pygame, you can DM me through Discord,
novial#1450. Maybe I can ask some Rutgers advice as well.

NOTE: pygame's y value is weird.
It's the complete opposite, if you want
to go down, you got to increase the y value.
If you want to go up, you got to decrease the y value.

NOTE: pygame's x value is normal.

pygame.Rect() DOES NOT SUPPORT FLOAT/DOUBLES
