I've played the demo, and I really enjoyed it. I like Alice in Wonderland inspired stories, and this one is pretty interesting and unique in it's setting. It's nice to see how the alternate world is actually similar to ours, but still not the same. I may usually rather very fantasy oriented worlds more, but as far as Alice based stories go, this is an intriguing take on it.
All of the characters are pretty nice, though I don't know if I'll try all of the routes. I'm also lucky because Emil is my favorite so far, so I had a couple of chapters to do.
Can't wait to play his full route!
