Glowgrass, written by Nate Cull for the 3rd Annual IF Competition in 1997, is a small game of xenohistorical exploration. It's mostly easy, mostly delightful, but it does have an eensy-weensy creepy vibe underneath. I thought for sure I must've written a walkthrough for this one already, but no, I hadn't. Until now. Enjoy!
[Note: This walkthrough is free because there's less than 15 locations in the game.]
