That's weird...
odd question but, is my VN the only one you're having problems like this with? I've person been trying to play other VNs (Fell, Tavern of Spear, Violet Memoir, etc) but my Android has been unable to open it as well...
I had a similar prob with another vn but it is different, imma try downloading again
oki
confirmed, i cant open file, and i don't know the cause
