This is an amazing concept! It is too hard though. I would suggest that you make it a flat surface, but I understand the novelty of making a round plant to base off of, so do what you want.
Anyone got any good strategies? Mostly I just take what I get and not focus on any specific thing, though I've noticed I've never made it to 20 or above that way.
Have been playing for a month, love the concept and the gameplay. Only have one suggestion. Maybe add an overkill feature where excess damage does something(don't really care what, no this wasn't taken from inscryption. Yeah it totally is)
