The Building 2D Games tutorial is amazing! I really appreciate the hard work that went into it. I went through Chapter 12 and everything was great until the circle collision explanation. There's a couple of errors pertaining to the direction of inequality sign, so this MR attempts to straighten it out. It's notable that the
