I just finished the game, with the "mercy ending". It was very enjoyable, especially the battle system, and the puzzles with the file manipulation. There is a big Undertale influence, and some scenes are clearly influenced by it. I really liked the final "mail" twist.
I keep my fingers crossed for a sequel, which seems to be hinted by the ending, and an official translation. Lvl1VillagerA's translation helped a lot, but the scenes lose their flavor with the automatic translation. ^^
I have a few questions, for the people who 100%'d it:
* Four crystals appear in the "gallery" room, after I completed the game, but they do not seem to have any effect. What are their use?
* I have completed the compendium at 91%, and it seems that I am missing some pictures. Does the Final Chapter boss have pictures, or did I miss some optional scenes, or are there some scenes blocked behind a "genocide" or a "normal" route?
* Is there a "pink bed" in chapter 3?
