I’ve been trying to remember the name if a game I played many years ago. All I can remember is that you play a colony on a planet/realm where there are ponds that get infected by spores that float across the screen. The ponds then grow and spawn if not defeated. When not attacking you can build things and need to create rocks/stones to attack the spawn and build other things. I’m sure that there were some buildings which would automatically attack spawned ponds or you found go into attack mode where you’d colony would stop building and attack the spawn/spores?! That’s about all I can remember, I’ve tried google searches with no luck!
