DAY 6
Today I was extremely busy with a bunch of other stuff so I only spent like 20 minutes on this, though it was a good 20 minutes. I just cleaned up some of the player's movement code, and fixed the weird behavior when you press both Left and Right keys at once (so now the player stops when you press both at once, instead of veering off in one direction and not stopping until you let go of both keys). So that's good; always good to have the movement system be as tight and responsive as possible in a game like this (or a game like I want this game to be).
