[58:42][Q&A][:speech]
[1:00:06][Does the current collision code support walls that are not 90 degrees?  Say if the wall is at 45 degrees, would the collision code still work?]
[1:03:28][Why not set a boolean value 'to be removed'?  It seems like setting the position to an arbitrary position isn't as explicit as setting a flag to say that the entity should be removed on the next update frame.]
[1:05:03][The rearranging of code did \[introduce\] some errors into the code.  Is this normal for daily coding?]
[1:08:17][Do we expect most entities to be colliding?  If so, does it make sense to have the flag be 'non-colliding' instead?]
[1:09:03][Then why set null position?]
[1:09:32][Would using a tagged union for entity references fix issues we're having with LoadEntityReference?]
[1:10:01][Do you have the whole big picture game architecture in your head at every point, or do you have to check what you did from time to time?]
