Honestly for me the hyper stuff is fine, especially since it's kind of the point of the game, but the growth may be need to be a tad bit slowed down since you can get to about really high heights insanely fast.
Edit: Now when I think about it maybe it's fine for where the growth speed is since it's mainly corruption that makes you grow really fast, if you don't go for it the growth is slowed down a whole lot without corruption and I think it kind of makes sense since the game is centered around macro, corruption and hyper growth so that could be why it goes so fast. I don't personally mind it though so maybe that's just me.
