It's a great little title with an excellent feel, some historical & educational content, and a great concept. It is best summed up as the type of challenging game that makes you want to look up a walkthrough or a FAQ for help, but your inner gamer niggles at you saying "Na, dude. You don't need to do that. Figure it out on your own! You know you can do it."
Indiana Jones meets Mega Man with a puzzle-ridden twist. Shades of CastleVania as well. A great buy on a steam sale near you.
