Game looks good -- Especially for early development stage!
Key art is very retro D&D / Lord of the Rings.. We likey!
Suggestions:
-- Rewrite the tweet to address both of your key target audiences: US and Europeans. (Americans probably won't react as well to the ultra dry humor style as Europeans.)
-- Flesh out the details to include specifics of your world. There's not much beyond generic information and it would be great to hear about some of the lore, characters, places and heroes / villains.
-- Great start to the Press Kit. You can expand on the world detail as per above, make the screenshots larger (add in more slides).
-- Try to hone in on a Unique Selling Proposition: What is really unique and interesting about your game that distinguishes it from others in that category?
