Great game, i think the biggest downside is the pacing but i dont know if thats just personal, maybe it is.
Did you played immortality idle? I think theres a lot you could do related to how that handles automation. This is "kinda" a flaw on progress knight as well, but progress knight has a faster pacing so this doesnt become a big problem.
If you dont want to follow an automation route, look at Idling to rule the gods cloning system or idle cultivation second soul system, its not an automation but you can do more than one thing at the same time making your progression faster.
In my experience- and opinion- a slow paced incremental game needs to have an automation for old systems or it either gets too complex or too boring
Now from another game dev to ya, create a discord asap.
Incremental community are amazing and they give A LOT of good feedback.
Good luck! Waiting for more.
