I don't wanna have to pay 7 dollars just to access the discord, why isn't it available at all of your patreon (free, 3$) tiers? Especially when you have public links to the discord in other places to join for free...
Anyway, the suggestion I was going to make was to add an orgasm mechanic; these pistons are going at these mobs for hours, perhaps the orgasm could be worth a small bonus of emeralds.
Maybe could make a preference for each mob whether they like Anal or Vaginal more to increase the rate of orgasms.
Lastly, there could be a larger impact on manual mode, like each mob wanting slower or faster, harder or lighter, depending on closeness to orgasm and their preferences and the auto mode would just be for passive farming emeralds or resources.
Bonus Lastly, maybe an orgasm produces a mob drop that can be used in crafting when the game gets to that point.
