As a testament that ACE Team's The Malstrums Mansion is a project which took twenty years to make, the developers have posted original design documents for the tribute adventure game on their official site. The docs include sketches of each room, location descriptions and even an items list. Though most of the text is not in English there is still a certain draw in seeing how much the Flash game is a direct translation of everything the team wrote back in the late 80's.

Their debut commercial release Zeno Clash will be released this coming April 21st, but customers who pre-purchase the game from Steam gets a generous 25% discount for being one of the early birds.
