You can play a little trial of the game, if you'd like the full Genmu no Tou experience. The arrow keys move you around, A is your main action button, B cancels, X confirms attacks, and Y turns the map on. You may not be able to read the text, but you can listen to the fantastic music and brute-force your way through some bats. If you like the way it looks, check out a bunch of screens in our gallery.
