Thanks! If I had the opportunity, I would spend all my time on development, but it still remains just a hobby. Once the Blender transition is complete, I intend to release a new chapter approximately every two months.
Regarding solo endings, I'll quote a part of a post I released that addressed a similar concern:
"-Question: Do I have a picture for the ending of the game and for the romanceable characters?
Answer: For the ending of Lycoris Radiata, yes.
For romanceable characters, the answer is both no and yes. The reason is that who you choose to romance will not have a significant impact on the main true ending. It will be separate, a final side story for that character, but not for the game itself.
Note: I know I wrote something about solo girl endings a long time ago, but at that time, I had no idea what that meant."
Hope this answers your concerns.
