The level cap is definitely intentional. Though I'm sure it'll be increased as more game gets added. As for a guide, that's probably a good idea. There's definitely some mechanics that could stand to have extra explanation and what not. Though I'll pry have to wait until I finish updating all of the games icons so that I can properly explain every status and what every symbol means.
For now I'll consider writing up something more general though.
Yeah I think we're probably like, maybe 2 to 3 versions away from that making more sense to do. Once most of the core systems are fully ironed out (for example, the skill trees and morality system are still just placeholders.) then I think community topics will make a lot more sense to enable. For now though most things other than hidden relics would become outdated very quickly.
