Interested in trying out some first-person dungeon action? Genmu no Tou to Tsurugi no Okite may never make it to the states, but you can play this flash version to your heart's content. The instructions have been posted below. Clicking over to check out the awesome music may be worth it alone.

Arrow keys to move, A to open things/action button, X to confirm things like attacks, B to cancel, and Y to toggle the map.

Try it here (takes a bit to load, be patient!)
