Having now played it, just wow. I think I got ending 8. Season 2 was one of the most memorable maps I've ever played, so to top that was really hard to believe.
I also fiddled with the audio quite a bit, trying to get the music a bit louder and the voices a quieter. It could've been clearer what settings were what there.
But those are tiny nitpicks, nowhere near in the way of me calling this the greatest map I've ever seen. You're a living legend, and I would've bought minecraft just to see your maps.
Checking back on my screenshots (of which there were many) my final score is 8/12 bobbleheads. Hah, "final", of course I'm replaying this!
