The game demonstrates a key concept about blind fighting: don’t believe the myth. Who knows who you are really attacking/killing? And of course arrows don’t go that slow and you don’t get to see these arrow icons when you are really blind. This means that people have to respect blind people.
This game is quite innovative in the concept of a blind swordsman and takes extreme liberties with what someone like that can really do. What you really need to do is just play with it and accept the fact that you probably wouldn’t be able to survive even one swordsman/archer with sight in real life if you were the blind swordsman, but here, go ahead and try to kill them if you can.
The game allows the enemies to spawn right on top of you if you are near the edges, so don’t fight there.
Minor issues are the lack of volume controls, which isn’t that much of a problem this time around since there is no music and there are only the weapon sounds and the breath of whoever it is.
