I apologize for the delayed response; during that time, we were extremely busy.
Various issues kept arising, including a team member in charge of marketing falling ill and the art development guy experiencing sleep deprivation, among other challenges. :((
After discussing and considering the workload and time management, we decided to release it at the end of November, hoping it will be on time this time.
I've just released the demo, and I hope you can enjoy it in the meantime! :3
