Awesome art style and choice of color palette (and I loved that turning off the lights flipped the palette). The scratches that show up on the vines when you hit them are really cool. My first time through I thought I was meant to be pressing E for the vines instead of clicking, so I got to experience the awesome failure animation :P
Music was really good, too. Very unsettling, and a great fit for the visuals (though I might have recommended making it a smooth loop since it's a little jarring when it restarts).
There's some clear religious imagery here, but I'm not sure I see the connection.
There are clearly some missing elements, but what is here is a really cool little experience! Nice work :)
