Ok, after 1,000,000 UberNumbers or so the game completely breaks, got an infinite number easily now. Apparently the display glitches out after treoctogintillion. Why would anyone still be here...?
Oh I see it has something to do with the unity webGL player, it's not that they are disappearing but that the game isn't scaling properly. Have to look more into it, thanks for the heads-up
Yes, it Is. Best anime/manga ever IMO
