I'm really happy that you took the time to play through and get the seven endings! Thank you so much and I'm glad that you had a nice time playing it ^^
Those mysterious happenings will be addressed later in the series, however there isn't a set release date for that as of yet. I'm also currently involved in a different project series that will most likely release before the next DFU installment comes out.
I hope you enjoy Make It Last as well! I really had a lot of fun working on that short spin off for a game jam.
Thank you again! ^^
