Yes, that trailer voice over is kinda terrible but the game seems like it could be really neat. Not sure if posting let's play type stuff is taboo but here's a longer form look at it:
That video is pretty much the first time I've ever even heard of it which seems like a shame because clearly a lot of effort has gone into this thing. Apparently the guys behind it are ex-Ghibli dudes? At least the art style seems to be heavily "inspired" by their work.
It's an adventure game with "choice" aspects so who knows how well that stuff is gonna hold up, still worth keeping an eye on I think.
