@Flarvex in that challenge the OP resets every time you collect it, so you only get the amount you earned last run. The way forward was indeed getting the "Double OP" Incrementy boost. Challenge is now done and I'm working on my last Factor boost before unlocking the next layer.
Turns out what I was missing was turning on my brain, Had enough OP for another factor shift. Now I am instead stuck at 8:2, need to get to 6.000e10 and can't seem to climb higher than 3.000e10. and useful advice is welcome. (clicking has no gain I can see.)
@IamPP Back again. the guide I referred to was as follows:
https://docs.google.com/document/d/1Tg01KHz-TjXISXjXIz5HGYG3bYIqpPuz3gjth2VzWAw/edit
Getting to 300 Boosters helped me clear challenge 7:3. Still completely stuck on 8:1 and 5:3. Even putting every single click into "increase ordinal by 1" I am nowhere close to pushing deeper. Feels like I am missing something but no idea what.
Ok, so I've been following the guide and it has, despite some small flaws worked, and finally getting close to the first endgame. First run on C8 1 and I am irrevocably stuck. I only get to the same number every run and it is far too little to push any deeper. Same thing if I try C7 3 and beyond that I only have C5 3 left which I hear is a pain and a half. so... how am I supposed to break through here? any advice at all?
Currently at 276 boosters, 6 Manifolds, and 242 686 OP (0 clicks left)
ok, so autobuilding is locked by barracks, and once you get them open you need at least 2k gems to make it better than Autoplacement. So stay away from that until you are in Robo-mode.
Once you unlock vacation progress turns extremely rapid. Might also benefit from being able to upgrade production in steps larger than 1. Clicking a hundred times on each button just to begin to keep up with production speed is just too much.
Finally, the green button on the Retirement page says "Retierment".
Ok people trying to answer a couple of things that keep coming up. like this is you find it helpful. Beating level 10 and 15 are both hard, but doable on the first runthrough. it will likely take some grinding though, don't expect to succeed at once. If you have spent all your coins or crystals on the wrong things and is helplessly stuck, there is a hard reset available but unless you've made some really bad choices it should work eventually with the right strategy.
Worth remembering is that the warrior is your tank, the Archer is your prime damage dealer. upgrade accordingly.
The overseer, once defeated, will appear in a small tab at the bottom/middle of the screen. It's a small white thing with a red/green button on it. That is where you can adjust your settings.
