Getting the Mercenary/Merchants to ally status in order to get the hard badge is just a grind feast. Hopes the creator of the game adds in a new quest for merc/merchants to reducing the grinding.
Great game, just one small complain though. It'll be great if you can cancel the information box by pressing space when you look at your weapons and equips
**SPOILER ALERT**
In my opinion, opening the doors to the prison is like opening Pandora's Box. On one hand, this will allow our protagonist to confront the archdemon and save the girl. On the other hand, the fiends will be freed into reality to wreack havoc.
Thinking back, if our protagonist didn't open the prison doors, the archdemon would probably escape and unleash even more destruction. Therefore, unlocking the doors was probably the right thing to do.
