New comment after playing and completing the current clan members.
The "increased brush size" upgrade for knowledge is just a flat mild negative. farming knowledge is not effected by how much of the ink you are spreading, but instead by the skill, and how long you spend doing it. Increasing the brush size currently provides no benefit and a very teeny downside by completing each talisman faster. also "cousing" is actually spelt cousin.
looking forward to new updates to play it some more.
i really like the upgrades that let you farm a small amount of another resource too. feels very rewarding.
