A very fascinating short tale. What sells the story is the sense of ambiguity. We don't know what happened to Sera, or if her sister can save her, but that's kind of the point. It's left up to interpretation and speculation while the focus is more on the action and suspense. I will say that I wish the story was a little longer, as I think there could've been more room for some emotional turmoil with the main character, but that's just me. The art is pretty good in terms of the character design, colors, and shading. The only thing I would critique is the backgrounds, which are rather simple or undetailed. Overall, I did like the story and it gave me something to think about. I'm interested in what else this creator puts out.
