This seemed cool starting out, but after playing casually for only a couple days I've reached a ceiling. I've prestiged 3 times now. Before my last prestige, I'd reached the Observable Universe, but never waited the ridiculously long time to unlock it. Now I've capped and am progressing too slowly for the game to continue to be at all interesting. It takes 5-10 minutes to be able to add one single point to Nova, and I'm not gaining any more helpers or points. And the rate at which we gain money offline is too slow to be of any real benefit.
I'm skeptical that there's much past this next hurdle. There's no benefit whatsoever to increasing your network cap to more than 45 networks, since you can't increase their bonuses more than 3 times in upgrades.
It'll be entertaining for a few days, but then it'll be time to move on to the next game.
