Under rating threshold (show) This was a good game but I find there's too much repetition of mundane underworldly tasks without autobuy of units.

Under rating threshold (show) How long does it take to unlock the 4th crystal... it's been a day since the 3rd was unlocked... why am I just waiting with nothing to unlock?

Under rating threshold (show) it would be nice to have some quality of life things, like visible countdowns for .... umm, everything.

Under rating threshold (show) The option for a third oyster seems silly, considering its cost (unless more purchase options become available later?).

Under rating threshold (show) Exiting out once before manually saving to my own device and realizing there was no cloud, no auto save.. hours lost was enough for me to stop caring about this forever; not just this game, but this genre. That's.. I'm good..

Under rating threshold (show) The "chance to apply vulnerability" doesn´t work correctly, i have 34% chance, im doing 40 hits per minute and after 10 minutes it happened 5 times :-p

Under rating threshold (show) @Dianoche Oh, I meant what e100860 wrote, there is a feature called "Worlds", that are separate from the factions (Undead etc.), but still somehow related

Under rating threshold (show) @VMDC quite true, I tried to explain the Obelisk easily but in the end the example was too simplified with respect the game. Thanks for noticing

Under rating threshold (show) Keep upgrading the runes, though you'll need to start spending the 10k energy to finish it instantaneously because otherwise you'll be waiting for literal years.

Under rating threshold (show) If the first 3 runes are at 100% , is there a point keep upgrading the runic prism ? All it is doing is speeding up the other three, whereas my other three are already near-instantaneous speeds.

Under rating threshold (show) The game is supposed to run constantly, but it seems like suspending the system to memory just pauses a lot of things, ignoring suspended time.

Under rating threshold (show) you only keep batteries, tokens, and gears after blowing up the boiler. For pearls, it is best to stick with producing red pearls and just create the higher tier pearls

Under rating threshold (show) The rune descriptions are inaccurate/misleading: they read "upon reaching," while they should say "while at."

Under rating threshold (show) Another tip for pearls: Use Sea pearls to upgrade Deep pearls.

Under rating threshold (show) Optimal Pearl Progression Strategy Basic Path: Upgrade Red Pearl to 50%. Collect 100 Reds → Unlock Blue Pearl. Repeat for Blue, Yellow, and Sea: 50% → 100 pearls → next tier. Deep Pearl (Scaling): Upgrade to 50%, then +5 Sea upgrades (boosts Yellow). Moderate upgrades on Red/Blue/Yellow (2-5 each), then collect. Maximize Deep Pearl: Upgrade Deep to 50% (guaranteed), +5 Sea upgrades again. Moderate Red/Blue/Yellow upgrades, collect. Final Boosts: Do "Collect Pearl" bonuses (if available). Boost Blue/Yellow x5, save 1k Sea & Deep upgrades. Time: ~2 days (Deep Pearl), ~45 days (full completion).

Under rating threshold (show) I have played this game... or something so close, I believe I have. There is no save file, so BotD will likely be skipped... as grinding seems futile.

Under rating threshold (show) Is robot faction gonna get new updates? How am I supposed to spend millions of energy when my daily cap is 27k? There needs to be contracts for robot faction that raises energy cap.

Under rating threshold (show) It’s similar to demons Boiler, but for undead faction. It’s the prestige mechanism for undead (world 2), needing 75 Bone flour to use. It’s what @Ccracker was talking about

Under rating threshold (show) @Ccracker it becomes a lot easier when you start resetting with the undead, not the demons. You get a lot more dark mana to start with so you can do it far more easily.

Under rating threshold (show) I really like how buying the later production units increases the one below it each second. In other idlers, the first buildings always wind up obsolete because of the one after it.

Under rating threshold (show) Worlds? I'm getting to the dark mana types and fairly recently finally got the mushrooms, but it would take weeks to get to the 40-dark mana point. I've got all the pearls (I presume), and I'm still working on the fourth rune. I don't reach the end of the monsters - generally Belial and Navj, Dagon and Locusta for the four types I have.

Under rating threshold (show) @Gadge What stage are you at & which world? And I agree about the runic prism. From world 3 on I have never completed it again and did not have to anymore. But for the first 2 it's necessary and completing the chest ~50 times, though very quick at that point, is very repetetive to finish it.

Under rating threshold (show) Same for me, did never spent $ for this, and was able to rich water world. If you find it slower and slower, then maybe you should change your strategy. The only point where I find this game boring is for having runic prism.
