Wow, that is a very filled garden. Little low on health, but I doubt anything is even able to stay alive for long enough to do so. Even maxed out the dungeon size!
Sickle drops I made the most rare, (being a 1/5 on tool drops), since I found them very strong to be able to repeat some strong seeds like damage or shot count to easily get full power. I'll definitely look a lot into the balance and how to change certain seeds so that actually farming them doesn't make you strong immediately. My favorite of this is the health seed, since you actually have a good reason to keep them on you to regenerate health.
