Glad to hear you are enjoy the route so far and many thanks for your support.
As for the two remaining endings, I would say they are the 'not good, but not terrible' endings. To get them I would probably fail one of the missions and complete the other, but if you want more details on how to get them, please email support@blackcross-taylor.com and I can give you more advice without worrying about spoilers ^_^
Many thanks for playing
