Ascension Upgrade Achievements
Might be just me, but i find it quite odd that you don't get an achievement for getting all Ascension Upgrades. Getting 1 Billion for the most expensive one alone is quite the drag.
I suggest an achievement for getting all Ascension Upgrades.
Or maybe multiple for getting certain amounts like 17, 34 & 68 or 17, 34, 51 & 68, but i mainly suggest the "Get all of them" achievement.
