This is an awesome piece of old-school RPG dungeon crawling game.
You are trapped in a book and must find a way to get out only to be beset by enemies preventing you from getting out, while searching for secrets to help yourself gain the advantage and delve deeper into the stories behind the book itself.
Combat is turn-based and its not just hack'n'slash, it uses energy for skills and each turn that energy will replenish slowly and this makes the combat even more interesting as stated in the description this involves strategy over grinding.
The dungeon itself is real-time and can go anywhere after that dungeon level has been beaten, explore to heart's content and find secrets opening up stories laid behind by previous owner and find out more what really happened.
I find myself engaged throughout the game fighting enemies and finding secrets for almost 15 hours, probably more if I spent more time in reaper's catacombs.
Although in all story and fighting, the UI and mouse interface is a bit clunky and could be improved even further, keyboard is the way to go for moving around and only use the mouse for opening doors and pulling levers and interact items.
I would recommend this game to anyone who likes fighting in a dungeon just to escape from being imprisoned forever. This game is a gem for those who likes to find things on your own as there aren't much clues to be found.
Oh and don't try 1980's difficulty.
