The game itself is a twin-stick shooter, with the feel of games such as Super Smash TV, with that whole top down view and moving through doors as you work your way through the game. The story of the game is all very simple. The princess and royal treasures of Cryptonia are stolen through a hole in the floor right in front of the king, so off goes his knight (that's you) into the crypts below to recover all of his shiny goods and lady for him. What follows is your working your way through floors of enemies that grow harder and harder the deeper you get, with each floor having secrets such as an arcade with mini-game, shop, and rooms full of monsters all wanting to end you, and not forgetting a boss at the end of each floor.
Overall: While Iron Crypticle didn't hook me as much as Tikipod's previous game (Aqua Kitty), there is something here for the retro guys out there who enjoy games like this, or those who like a challenging gaming session. Personally, I would play a couple of games here and there then turn it off, but that's just because I don't have time for a game in which death means doing the same section over and over again before getting to the place you got to previously.
