I really love the narrative, art style, aesthetics and musical score - just superb.
But i can't shake the feeling this would play out better if a full on visual novel and you ditched the slightly awkward feeling mechanics of gameplay / puzzle sections. They feel clunky compared to the dreamlike relaxing approach to the theme.
Don't get me wrong - these are just my personal thoughts! Wouldn't want anyone put off and missing out on the story :) and will certainly be keeping an eye on this.
