It’s quite peaceful tbh, the gameloop still feels fairly vanilla. I haven’t done a proper “intense” Botania-only playthrough yet, where you automate most flowers though. My playstyle is quite laid back, where I’ll often find myself fishing or something while my Hydroangeas chug away. Farming manually to feed a Gourmaryllis or doing nether trips for a Thermalily, Botania complements how I play the game well. Only suggestion would be to remove half of the alchemy catalyst recipes because they circumvent the need to explore for resources (wood/sapling cycle, crop cycle etc.).
I’d suggest checking out WinryLive’s Floramancer playthrough if you want to see what Botania+ is really capable of.
