There's so much I adore about this game. I love the style, graphically it's really pleasant to look at. The story you've got building up in the background as you beat each level really inspires the player to keep going as well. Clever game mechanics for sure!
I did get completely stumped as I got further into this demo though, and frustration took over as I tried (and failed) to get past a certain set of fiendish puzzles. Perhaps I'll try again at some point (I did try a few other things after initially giving up but I didn't get anywhere), but for now I'll just be happy with what I managed to complete!
I'm sure this game will be super successful, I just wish I had the brains to match it =D keep up the amazing work, this was honestly a beautifully made demo.
