The game looks really promising.
Going off of what I've seen so far, I'm guessing the potions will work off of a tier system like DnD or Pathfinder (minor, lesser, moderate, greater and major). What I hope is that each tier gives increased residual growth in addition to what I assume the tiers would already do, i.e. increasing the amount of growth with each tier.
Unfortunately the dialogue and some images are a bit rough, however this is more to let others know than to drag down the dev. I can tell they're enjoying working on the game and that's honestly one of the three biggest parts of game development in my opinion, the other two being managing scope creep and quality assurance.
All in all, kudos to the dev, this is fun and I hope to see it go places.
TLDR: Game is a bit rough at some points, but it's clear the dev is putting their heart into the game, and it's pretty fun too.
