Under rating threshold (show) Re those optional boosts on the Boiler and Obelisk, to spend tokens on 1.5x multipliers: Note that they are NOT permanent; they reset with the next restart. Considering how hard it is to accumulate tokens, it looks like a big waste to me. Learn from my mistake.

Under rating threshold (show) This would be more playable to me with my eyeglasses-wearing face if there was an option for an alternate, easier to read font. I keep wasting my waste (lol) on leviathans because I mistake the 0 for the B for billion :c

Under rating threshold (show) I've just spent 10 batteries trying to reach 2.000 dark mana, so that I could unlock Warlocks. Once I got to that value and clicked the button I realised that I needed 20.000 dark mana

Under rating threshold (show) after changing worlds, runes reset. Runes take a lot of time that I could have spent working more in the heroes. I am confused by the multipliers for pearls. In the picture of the monster, it shows multipliers. Those mulpliers are way lower in the picture than what is says in the pearls page.

Under rating threshold (show) This game is like Antimatter dimensions. Neverending story of somehow getting clue how to overcome next milestone and grind enough to get there. I love it. Half active/half IDLE.

Under rating threshold (show) In case anyone's wondering what final result of the Runes section is: I finally got the Runic Prism to 100%, and it says "Completion effect: x2 runes power". Everything seems to be locked out now, and nothing can be clicked, so this is probably a final x2 effect unless something down the line opens up something new here.

Under rating threshold (show) for how to get 100% Runic prism: you need to get far enough to be able to easily reset with the chest (drowner), every time you reset with drowners you get energy and you can use the energy to speed up the making. runic prism's energy caps at 10,000 energy so, I as soon as I reset with chest I can progress 1% at a time.

Under rating threshold (show) Fun game, lots of charm, with upgrades that feel impactful. I look forward ot coming back to this after being offline for a while. Only negative point was also mentioned here, the runic prism does not progress offline, and takes hundreds of hours to complete

Under rating threshold (show) A timer on mushrooms would be nice. I know the online save onlys works on one computer. If I move to another I can't pull the online save. So I have to move the manual save file to my other computers.

Under rating threshold (show) antivild that seems like enough as your rune crafting speed is fast enough when you have that much runic prisms

Under rating threshold (show) That theory seems wrong. The game just pauses as soon as it is not the main window. If you deactivate additional offline calculation, you just don't get the tiny bonus from being offline. No offline progression is bad, but leaving the tab open while watching a movie or smth should be possible...

Under rating threshold (show) i have a theory about why you can't get progress when you aren't on the game which is the "additional offline calculation" setting in the extra settings as i have disabled it and it seems to work off screen now for a while

Feb. 07, 2024

Under rating threshold (show) The fact that everything basically pauses when you click away from the screen, especially runes with their insanely long timers, even if you keep the window open in the background, basically makes this game mindbendingly frustrating. Why not let the idle game idle?

Under rating threshold (show) @chritianG11 It would not let me buy a spell until I bought the cheaper spell for some reason. I need a ton more to get the next slot too. :-(

Under rating threshold (show) @richard233 Max out the crystal power contract, then get the energy cycle spell 1st (600 total dark mana, 100 for the slot, 500 for the spell)

Under rating threshold (show) I see an error playin in Chrome: The creation of blue gem is instant, probability is ignored and invisibly set to 100 and its creation cannot be automated. Also, I see inconveniences: When a creation is limited, I don't see, by what it is limited. To find what creations can be done, I have to check all positions in the game. No warning appears.

Under rating threshold (show) 2nd oyster appears to have no value. I created it, but the pearls were already capped and I don't see any increase in productivity.

Under rating threshold (show) is a 2nd oyster actually of any use? I mean, I have all the basic pearls at 100% and I've not yet unlocked the warlock's faction, but likely will in a couple of weeks at this rate.

Under rating threshold (show) If you don't mind a bit of a hassle, you can progress with Runes and everything else while doing other things by having any other application and browser window size adjusted to where they cover 99% of the screen. This isn't the only idle game to have this problem, like Grow Defense. Anyway, if you do this, the game will consider itself "not covered up" to stop the normally halted accumulations. BUT that doesn't mean the developer should stop trying to find a way around this.
