I've never known a great idle game without a prestige tier. This is a good idle game, but you gotta shoot for greatness. Also, just me nitpicking: The number is "googol", not "google".
"A faster ship can can zip between planets!", as well as what people have already said. This game may not be top quality, but at least it's getting somewhere.
