Tooltips are your friend. You can use tooltips when mousing over the different category names (Systems, Weapons, Cool) and explain what each of them are for. Then, once people know, they don't have to mouse over that and be bothered by it. It's better than needing to unassign all starfighting to read your message.
Whenever I am at the top of a page in the rankings, the game will show the wrong page. For example, if I am ranked 161st, the game will display the page showing ranks 151-160. This has been happening both for the weekly rankings as well as event rankings. Please fix it.
Spending fuel is too slow. It takes forever to burn through the average of 500%+ fuel that you get every day. You get 100% for free, ~250% via daily TCs, and at least ~100% more from daily log-in bonuses, missions, codes and spins. If I want to stay on top of that, I spend dozens of minutes each day staring at the boring war zone screen. I can't even put on my autoclicker and go away, because every 10 stages my progress gets interrupted by pvp. Even if I spend precious gold to get x6 damage and fuel use, it's still much. It makes me want to not play this game anymore. Please add some way to make spending fuel painless. I suggest being able to set your own multiplier (only it doesn't work in boss fights).
I really hate how the daily mission that says "win one battle" actually means "win the current battle and the next one". It seems disingenuous and deceptive. Can you just make it say "win two battles" without changing how it works?
You could add a thing where you get a guaranteed jackpot from the wheel every 100 spins or something like that. That way, even if you get crap from your spins, you still feel like you're progressing towards something worthwhile.
Please, for the love of god, show the expandable resource summary on the dungeon victory screen, so I can see whether I need a specific type of crystal before I choose.
It would be nice if you could override the automatic usage of skills on a case-by-case basis. Let's say the enemy has a sliver of health left and you want to save your powerful attack for the next enemy. You could let the player click the button to deselect the special attack before it actually happens, so it uses a normal attack instead. The automatic behavior would then go back to trying to use the special attack on the next swing.
Actually, it seems like it's the ordinal points display that's causing everything to wobble, so that's where you would have to look if you were going to deal with this screen shaking nonsense.
The screen shaking and quaking as terms are added and removed from the equation feels powerful, but it can also be annoying or inconvenient. Maybe you should set it up so the equation at the top takes up a certain amount of space with or without all the nested superscript, so as to not constantly change how much vertical space it takes up.
The splash screen has scroll bar. I scrolled it while the game was loading, and now I am on the main screen which is similarly scrolled, only there is no longer a scroll bar to move it back so I can see everything. Also, it persists on reloading. Nice.
Why are you using the same notation you use for large numbers for the gold counter? It's not going to get that big. Right now, I have 3.24K gold. Why are you hiding the final digit from me by replacing it with a K? You're not saving any space that way! Please make it show the full number, and in general "K" should not start being used until 5 digits or even more.
Not being able to affect or speed up adventure in any way makes it seem rather underwhelming. No way to see what you might get, or what the chances are. As a late game player, the amount of money you get is pitiful, and you seem to get money a lot. If this is an unlimited source of rubies, I think maybe there should be an upgrade system using it that lets you improve adventure stuff.
When you switch back to the organization screen in the event, all business buildings show a deficit of resources before the first tick happens. I recommend not having the game do that, since it can mislead players. If the game can't properly display the status until the first tick, instead display no deficit on screen switching.
That "one of your buildings has no input resource" message should really update on every tick. Specifically, it should go away on the very next tick if you secure a supply. This thing was extremely confusing until I realized that message doesn't update often enough to give you good information.
Could you maybe let the button to reroll the daily quests be there whether the current quest is complete or not? I would like to be able to try for better rewards even on quests that insta-complete, or on the final one if I still have rerolls left at that point.
Please make the event buy quantity button remember its setting, and also hardcode in an exception for the OCD buy settings to buy 1 water bottle factory if they are at zero, to get the run started.
The buy all buttons on the event screen should look different (light up or something) when there's something to buy. Since you have to scroll up and down to see everything, that would be helpful. Also consider coming up with a collapsing function that omits some of the information, but displays all items on one screen, preferably with the % of production and cost to buy + buy button as the most important info / features. Dunno if that can be done, but it would be nice.
In the challenge screen, number of challenges done / possible should be written next to the buttons, so you don't have to hover to see the status of the challenges.

Just FYI - I've added all your notes from comments into our to-consider list. Quite some we already have there, but some are new :)
