Wow, this is an ambitious game!
Seems like a lot of content for 1 month of dev. I felt that I had died enough after getting the wings, so I didn't win. Cool setting and story, I guess some pain could have been spared by hinting at how many sigils were needed before finding out the grim truth from the green dude :D
It also took me a few too many deaths to get the sword. It felt much better after that point!
Really impressive one-man-show, well done!
