Under rating threshold (show) so when you use the Bonemeal converter, it does not count the converted bone meal toward the obelisk nor does it count toward unlocking the obelisk. Is there a purpose for the black magic spell if that bone meal wont count for anything? Or is this just a bug?

Under rating threshold (show) I unlocked a slot in the spell book thing and clicked the swamp ritual before the lock fully disappeared. Now I can't seem to buy the swamp ritual even though I have enough dark mana. I tried adding a different ritual and unlocking another slot, but it still won't let me get swamp ritual.

Under rating threshold (show) If I select the option to hide maxed out contracts, could the developers please make the remaining contracts collapse to the bottom of the list? Scrolling through mostly blank space gets tedious after a while.

Under rating threshold (show) @1firelord How did you manage to take that long! it only took me a week or two f2p to reach the first boiler explosion. Also you should make sure you look through the contracts so that you don't gimp yourself from the second run into the third since there is a contract for 50 that makes Runes permanent.

Under rating threshold (show) Okay, game is decent. I'm playing free to play (f2p) and i spent a month getting to lvl 6 demons and lvl 2 mage, and lvl 3 undead. That was with runes and oyster. This is taking way to much time and I seem to be capped. I got my first boiler explosion and guess what within a day I'm back to what took a month. Capped and can't do jack. I literally just log into to collect trash and leave spending mana. 2/5 however how about a time warp button. For like idk months at a time.

Under rating threshold (show) I don't like the random chance of pearl creation, but I love that it tells you what number it rolled, so you can see how much you missed it by.

Under rating threshold (show) Why not have the runes work similar to the pearls? Have the ability to sacrifice like 20%, 30%, 50%, or 100% of a rune to automate creation. It seems the only reason pearls are automated is because of the random chance to obtain one.

Under rating threshold (show) Was crystal power cut by about 1/3 in the last few days? I have 1 of contract D. Last i checked that was 12X for crystal 2, but today it is 8X. Dark mana conversion looks lower too.

Under rating threshold (show) Runes system is just a hindrance. Runes should be created automatically by the game as an idle activity; it shouldn't require the user to always be active and clicking the button.

Under rating threshold (show) Always there is something that will keep your progress extremelly slow... right now for me is the raw mana that requires energy to produce waste. This game is so slow to have any progress it is not appealing

Under rating threshold (show) Blow up the boiler probably means this game's reset/rebirth/prestige system, and requires about 1e94-95 gems. I think. Haven't done it yet.

Under rating threshold (show) Fun idle, with nice art. I'm stopping now at the runes step. Staring at the screen waiting for progress is a no go. Can't switch tab or it stops, can't put in offline mode or it stops. Won't be coming back to check if improved, but I had fun.
