Great game!
I'd just like to report a couple bugs I noticed. They aren't serious, just some slight visual weirdness. I was running the game through Firefox, so I can't guarantee that these apply to the standalone version (or Chrome)
First, curses appear to leave only when the next customer arrives, leading to Skee here wearing a cursed amulet (makes me wonder a bit if and how much petrification would affect a skeleton)

And also the magic glow shader (I assume this is a shader) seems a bit broken with some items
