I love Frederick and would die for him. The game's overall style was impeccable. The sketchy, pencil (maybe charcoal?) art style WAS AMAZING! It's always a treat to see this kind of style in games.
I loved that even though the game's color palette was black and white (for the most part), Frederick popped out against the dark, ominous dungeon background.
The music was also fantastic too, excellent job in choosing the music! Each track matched up with the scene's perfectly. My favorite HAS to be "Slow Motion." It's gentle and slow. Aside from me being an absolute sucker for slow songs with strings + piano involved, the track really encompassed the warm yet somber atmosphere the game had going for it. Frederick's would look at you warmly and without judgement, meanwhile the player, may have had other intentions and could easily eat him invoking that somber tone I mentioned earlier; invoking a sense of guilt.
Anyway, enough rambling! Fantastic job. I'm looking forward to playing more games from you!
