You have crafted an amazing game. The writing is incredible, engaging and relaxing with its command of language. Dave's reasoning is a joy to read, he comes across as an excellent scientist and flawed with his prejudices, which he (so far as my progress) he has not quite overcome. But then, it has only been weeks since his misconceptions have been challenged and his world view overturned. Each character, even the silhouetted ones, like Grace, come across as genuine to what they are supposed to be. The music is well chosen and also relaxing to the point I sometimes just lingered on a scene to listen. The combat system works to move the story along and is easy to understand and best of all for people of low reflexes like me, choice driven.
My only criticism is the experiment Fun conducted should have been a choice instead of forced upon Dave. While its end did prove its point, it was still forced and that violation was hard to look past for the dialogue that followed. Other than that, an excellent work that I look forward to English version 0.5 when you get to it. It will be worth the wait. Thank you for producing this game.
