Under rating threshold (show) @kikhaky im unsure of any other websites that would host the game, but i believe you can download for free from Steam and import your save there which might be more user friendly for you.

Under rating threshold (show) NOT ONLY is this new UI just a ripoff of other (worse) (maybe not anymore) sites like CrazyGames, but the new UI is also strictly worse at displaying critical information. Why do I need to scroll past the description to see achievements? Roll back these changes for the good of the site.

Under rating threshold (show) Kongregate keeps messing with the layout and now it's worse than ever - the game is cropped. Idk why kongregate thinks it needs to continually rebrand itself, but it just keeps getting visually worse and worse. I've been playing this for a few years and it just keeps getting harder to use. If there's another site we can import saves into let me know.

Under rating threshold (show) Has anyone gotten any of the artifacts that give +5 to a resource now and +5 after restart? Im curious about how the "after restart" works. Will it just be an extra 5 after every restart or are they cumulative? Like 5 after the first restart, 10 after the second, and so on...

Under rating threshold (show) Changing from normal game to the next gate was my biggest regret on the game, it says costs rise 1.3 but in fact it rises 20x what makes the game very imbalanced with a wall that kills the will to play.

Under rating threshold (show) I kept it all on the first boiler because it applied the bonus to the amount of waste as well as prestige, allowing for much higher growth in the runs. Pushing up into the undead contracts helps with the challenges a lot

Under rating threshold (show) Not sure why did I swap this early for the second boiler, but I think it gave way more prestige. I have done a few challenges, but I don't think I'm ready for most of them. I have that artifact but I didn't know I could use it for that achievement, lol. I have just activated that setting for the right mouse button.

Under rating threshold (show) @marcius Contract Q up in the CEO cabinet focuses on Boiler B. I havent even touched that one yet. Just kept all my gears on the first boiler until it seemed i was bottlenecked by the undead. Swapped over there and did what i could for a while. Once that side is built up some it makes it a lot easier to knock a quick prestige out so the restart from the challenges are not such a set back. Also, spend the 250 tokens on the artifact that clicks 25 times a second. You almost need it to get the challenge done that rewards you the same feature. You get your 250 refunded. Then go into the settings, interface settings, and check the box to make your right click act as shift+left click. Biggest time saver.....

Under rating threshold (show) Rondrian You prestige differently for each faction. At the beginning you will only be able to do it with demons. To do it you must reach 75 hell ashes. When you have them you will unlock something called the boiler (on the faction's tabs). Later on, you will reach 75 on the other factions' equivalents, like bone flour or magic powder (not so sure about the magic powder because it's really hard to reach that amount.)

Under rating threshold (show) I have a few, but it sucks once you do them because you start with no waste/dark mana. I have a question about the demon contract J. The first level enhances the first boiler. Do the next level or any other enhance the second boiler? I usually just go after the second one.

Under rating threshold (show) You're honestly not too far behind me i think, maybe a little over a month or so if i remember right. I generally use the free gear resets to switch up what im farming, moving all my gears from boiler to obelisk and back. Before you know it you'll have enough to pop the chest for the first time. Dont do what i did and forget about the challenges for a while. Pretty helpful those.

Under rating threshold (show) I see. I'm far from that, I think. It currently farming contract points from the obelisk. The bottlenecking seems to come from the drowners, of course, but also from the demons (a little less, tho). But I have all the gears on the obelisk so I'll farm that for a while, then I may go back to farming demons' contract points before trying to get the drowners, which feel unreachable right now.

Under rating threshold (show) @marcius along with the prestige, each faction will also give a bonus to a resource upon reset. Once you start opening the magic chest the last rune wont seem as daunting

Under rating threshold (show) @JohnCrane I'm talking about the last rune specifically. I don't know if there is a way to speed it up or not but right now it feels pointless to dump so much energy on it.

Under rating threshold (show) I'm 6 months into this game. Yes it's frustrating at first that some progress stops offline, but I think that's a deliberate feature - there's eventually a contract/spell/upgrade to resolve every temporary annoyance. The game is mostly about grinding prestige. I like figuring out how to optimise each run as the game parameters evolve, and it means nothing can ever go catastrophically wrong. At worst you just abandon that run and start the next one, maybe just with less starting waste or dark mana than usual. Apart from tokens everything is fairly easily replaceable, and most things have a use at some stage. This game takes a lot of patience: but I love the trial and error aspect, and the steady trickle of new elements introduced as you progress. It's also fun flying in seconds through stages that previously took hours or days - very satisfying. The option to export and import saves was very welcome too, when I had to replace my laptop.

Under rating threshold (show) It works for me. I've recently reached the undead's threshold for contracts. I have automated the demons' upgrades which really helps my fingers haha. So now I'm trying to get more undead contract points (I moved all the gears to the obelisk, which would be their boiler) and I'm trying to unlock the warlocks to see what they offer. I get like 350 dark mana for each 2500 energy. I'm using the energy boost from the grimoire.

Under rating threshold (show) @JackVermicelli you don't need to disable that because when you get that upgrade (to autoupgrade every 2 seconds) you have already taken the previous upgrade, which makes upgrade cost-free.

Under rating threshold (show) I see a lot of people complaining about runes, prisms, and pearls not progressing in their production, and I want to echo this sentiment. It's a very unreasonable design aspect. Not only do you have to have the game open for progress to be made on the production of these things, but you can't even go to a different tab or minimize the window and do other things! I've tested this. The game developers seem to want your eyes glued to the screen for literal hours watching a progress bar crawl from left to right! That's unreasonable at best and hateful at worst. Nobody is going to want to do that even if they've got the time for it. Even the most bored person on earth can think of better things to do than sit for literal hours just to stare at a slowly moving progress bar so that a number can tick marginally upwards on what is essentially a pyramid scheme simulator.
