This is a great game, small but cohesive and everything tied up neatly.
I think i have the feeling like the game slows down when the black hole turns big. I’m guessing this is normal, because the camera moves away and of course things will move “slower” from afar, but when starting again from the smaller scale then i have the sensation of things moving faster. But this is a very minor problem, and possibly only for me.
I like when games have this comic-like dialogs inside the narrative :)
