How do you playtest your own work?
Last game, I just played the early chapters over and over, and then used a save system when the game got too long to play through. I wasn't crazy about the save system, but it did help.
Essentially, how do you test chapter 6 if all you want to do is play that one chapter over and over? Do you just tear through chapters 1-5 a hundred times, do you use a save system, or is there some clever thing I haven't thought of yet?
