This was just released a few days ago. I've only played the first mission, because I don't have time right now, but it already looks like a very charming game. The voice acting and music are surprisingly good too. There are some bugs such as the options menu freezing and vsync not working for some reason, but you can still change stuff in the game's config file. The developers intend to keep supporting the game and they're working on multiplayer. If you like Dungeon Keeper, you may want to check this out.
