Really cool little game!
It reminded me a of Potion Craft, although I really like your innovation on using unit movement management as a crafting mechanic, that's really fun. Initially I wished you explained what the different spores behaviours but it was actually fun deducing it! I did have a bit of trouble corralling the little dudes around, but I'm generally terrible at micro and was playing with a trackpad. The purple dudes we're such a headache >< altho in a good way maybe?
I really liked the music and the voice/SFX were great! Gave a lot of personality to the unruly little buggers.
I'd love to see some meta game, like cash for delivering mushrooms and maybe the ability to buy consumables that help me (like a AoE that makes the spores stop moving for a few seconds, or a wall to stop them from running off the screen).
Last random comment, I wish I didn't partake in poisoning people if I don't want to, altho it is on theme for mushrooms.
Overall really cool game! We'll done!
