Thing Trunk’s innovative isometric deck building hack and slash action RPG Book of Demons has been updated with all new end-game content, and the developer has also released a demo.

Update details:

More Challenging End-Game Mechanics – From now on, bosses will be immune to certain cards, forcing players to adjust their strategy on encounter. This takes advantage of the game’s hallmark feature, a card system that unifies spells, items, skills, and character stats.

Daredevil Mode – Players prepared for an even greater challenge can try Daredevil Mode, which adds a brutal permadeath mechanic.

We previewed Book of Demons back in August and found out that it’s one of the most polished Early Access releases to date.
