Just to make sure I understand this right:
So IIRC the Kickstarter was for a single animated special?
The Amazon later stepped in and said "Hey, we're gonna make a series!"
The rewards in the Kickstarter are for merch: some music, a ringtone, playing cards, art print, dice, a bag, pins, etc. unless you pledged $2.5K for a private screening. That seems pretty clear on the KS page. Do the backers get to see the animated special for free, as well as the rewards they pledged for? Or was the special replaced by the series?
