No-commentary playthrough:
This was a fun one, but I must say... Allowing the player to retry the ending from the time you equip the gun would be just lovely. The problem is that the break in/board up section of the game, while fun to play on the first go, isn't challenging enough to remain interesting on repeated playthroughs. So it ends up feeling like you're going through the motions for over ten minutes just to get another crack at the bad guy. Perhaps something to consider.
