Fantastic work and so much delight and surprise that I wasn't anticipating. As I played through the demo I kept discovering thing after thing, repeatedly saying to myself "It's not over?!" All the art, all the atmosphere from the music to the dialogue are consistent, personal, and speak to both the spirit of the game and the artistic vision behind it. I got whupped a lot but never in a controller-breaking put it down way. I always wanted to get back up and chip away at it. Also...the gun is my favorite.
Now the bug. *SPOILERS* if you're still trying to play through the demo.
In trying to fish, I did find an error that crashed the game. I've attached a screenshot of the error here.
