Still very vague. Look, the problem is: what is it exactly that made so many people click this shit? Maybe the belly top highschool kid with a bloody axe and the overall identification with that highschoolkids? That there is like zero information about the actual game? The Horror genre?
Maybe a good idea would be to make a small comic-like fictional story with Kajia art that could take place in the game. But this would be a lot of work and probably not doable for this Kickstarter, maybe for a future attempt.
its not really a mystery. it was short, simple, drew on something most gamers probably understand (left4dead infected spawning mechanics, tf2 classes, just all huge rip offs honestly) and posted in a simple, straightforward, visually arresting way. read it in 5 seconds, grasp the concept, think its cool, deceptive to think its innovative while just using shit we already know and like to sell it as reliable, +1 it and share it to someone else who likes the same shit.
its a swift pitch, sounds good feels good, doesn't trigger any sort of kickback like suspicion, doubt, failed expectations, so forth.
besides, clicks, views, shares are non-committal. donating money is. 15,000 people saw it sure. i doubt even 100 of them would donate real money. and at least 10,000 of those views will be by ppl who forget they ever saw it the next day and move on to the next attention grabbing high concept bullshit that hits the right notes.
its all based on i guess social psychology. I will continue pimping myself as a "freelance social networking/web 2.0 messaging coordinator" to m:bg team if anyone ever wants a real taste
