Game would have been fun if the controls worked. Sadly the snake controls really weirdly for me.

The update I mentioned has come out, and we've not only refined the controls/snake physics a bit, we've also added sound effects and particle effects for audio/visual feedback when you are travelling through something where you can control the snake (ground/paintings). If you get a chance to try, we'd love to hear what you think!
