Update from the dev (translated):
Regarding Dungeon and Bride's release date, the end of April is a little tough. I am sorry. I've been doing my best in my own way, but I've been having trouble with my private life... I want to concentrate on my work, but I can't concentrate on my work, and it's very frustrating.
Future plans are undecided for the time being. However, it won't last that long. We will report back soon.
We plan to release a final trial version that also serves as an operation check by Golden Week. I would like to make the save data usable in the retail version as well.
I'm really sorry this time. We sincerely apologize. (Added on 4/3)
Well, at least a new demo might be released by the end of the month.
