i think i get it
well, i went back and watched the others, and now i think i get the gist. Basically, he has been fighting versions himself from different places in time all along.
The first time he goes back he ends up in the purple tofubot or whatever, and gives him past self a tofu capsule while in disguise. then he gets attacked and beat by his past self, and encounters his past self again, only to get punched in the face and almost shot to death. After that he re-visits the oracle after waiting for his past self to leave to follow the map.
I assume that in TOFU4 (or whatever it will be called) he will go back in time a little further than the last time, end up in the tan tofubot (from the first video), and will get killed by his past self. Then is he dead?
Did i get it? I think i got it mostly right, but I can't say i know what the giant white tofubot at the end is.
Anyway, after all that, great series! You got me puzzling over it, which is a good thing in my book.
