I got to a point where I seemingly wasn't anything I could do, had no idea if that was the end or if I was supposed to wait for something or if the game was bugged out.
i believe i had the same issue as you - was it just the window with the spheres floating up towards the galaxy? mines been sitting there for a while, it seems like a bug
I replayed it, I think maybe if you don't complete every single upgrade prior to hitting the final thing it doesn't cue the ending. I did every upgrade on every tab this time and it ended.
