That was absolutely mesmerizing to watch and play. Music and visuals have set the perfect rhythm, encouraging me to try and speedrun. I've enjoyed seamless introduction of new mechanics and obstacle, and a snippet of story in the end of the demo intrigued, interested to learn more.
I am kind of scared, yet excited to play full version, because I fear that level of mindfuck will only increase an I am not sure I can handle it :P
Anyway, thanks for great experience and good luck!
