Steam review snapshots
The world is big and youu'll explore multiple areas full of secrets and puzzles while unraveling the crazy story which culminates in…The charm, the looks, the atmosphere, almost everything is great.All voice acting is also displayed as text, so the game should be playable for Deaf and HoH gamers, though you may…Still there's qualities : it's beautifuly cartoonish ; the makers made big effort in it ; it's in Lovecraft universe.Why it fits
