Incomprehensible
Being someone who has no clue what Dark Souls is, I might not be in the position to say it's an incomprehensible flash.
I literally didn't understand anything that happend in this flash, so I'll just compare it with other flashes about games I didn't play. For example I never played Skyrim, but yet I can comprehend everything the author is trying to tell to me. This stuff is undoubtedly very cryptic for something who never played this game before.
You've excluding a big audience this way. Look you've obviously put a lot of work into this, but I really didn't understand anything that was going on. But yet I can understand things like... Metal Gear Awesome and such, and yet I haven't played that game, so please think about this.
