Theres a good bit more beyond that, but it is very grindy.
I'm at supernova 65 right now, and its slowly getting towards another wall.
Now 83, yeah, its an annoying wall...
And now endgame reached!
83 isn't a wall, and in fact is quite close to where you should be rampaging through supernovas. You're missing an upgrade somewhere, or some new upgrade has released since.
