This looks like a nice concept, very interesting implementation of the Swarm theme! Balancing out which spores to use for actions and which ones to save for scoring seems like a nice
The mechanics are very thematic, the way the faction works is easy enough to understand, good job on that! Among the things I like are the option to build mushrooms in clearings without your warriors (should you want to...), that seems very flexible. Plus the use of artwork from other Leder titles, that's clever!
Is there any relevance to the order spores are placed in the spore chamber? It states the way it should go in and out a couple times, but I can't find a reason for it.
I'd be curious to see how they'd comeback from being wiped, it seems like a slow and arduous multi-turn process.
The description for Mind Infection in the lore text sounds awesome, I kinda wish there had been something more/cooler to it than just moving a single enemy warrior each time.
Overall, nice job creating a very neat faction here, kudos!
