I can't tell what is a bug and what is purposeful game design but it's pretty funny. I only managed to get my Vazeglina up to 90 and then ran around for a few minutes spreading blackness to the rest of the map but couldn't find anything else to do.
But I do enjoy the limited visuals, you made some pretty cool effects in the background, though I am curious, is the main character supposed to be a purple texture-missing thing?
Very eery, pretty cool!
