Overall a fun little game, liked the funny options and really cool statistics. The game also looks and sounds very pleasant.
Didn't like the clicking mechanic honestly, my fingerst started hurting after a while xD I would suggest either introducing a keybind e.g. X as an alternative to LMB or auto-clicker upgrade. Also would like to see keybinds for the upgrades e.g. 1, 2, 3, 4, 5, 6.
Also didn't understand what the Spawn radius was doing. I focused on child count mostly, since I thought increasing the spawn radius would just spawn spores further away from where I was cliking. But at level 2-3 I realized that child count matters only if the Spawn radius is also leveled, which feels odd to me.
