I just finished playing this and got the good ending on my first try thanks to the hint file
Well done on a very well finished game
The only feedback I have concerns the (good) ending:
So everyone just finished the big battle, and Sonya and Kai and Jackal got to stay on earth and all was well... and the mood immediately turned to lighthearted with the bachelors all asking Sonya whom she'd pick amongst them. It felt rather... odd...? I mean, just a while back there was all the fight and battle and people getting killed - so the humorous ending would had occurred amidst a mountain of corpses...? Plus the ending never mentioned anything about Milo - did he survive the whole thing? Did he die regardless? Why was there no reaction from Sonya? I mean, she spent the entire game looking for him and it's as if after the battle she just... forgot about him. Nana as well. Maybe I missed something?
Other than that, well done
I got addicted to it and was playing it the whole weekend. Looking forward to your next game
