I may not be a giant ant, but I can confirm that running in wheat is pretty awesome. (the spanking that I've gotten after doing that as a kid, not so much)
so they just left the dungeon-wave-infected tunnel open? where non-stop monsters spawn and fight about? by now the village is probably grounded already...
I am so damn happy for the colony, and also huge respect to author for such dynamics in plot, diversity of locations and interesting interactions. Incredible job.
