Ok, I cleared the game with the "stolen" ending. After I learned the rules it was pretty fun. Using sound to manipulate enemy behavior is cool and I really like that the game assigned a name to every person I murdered.
Sometimes two enemies stand on the same tile and the game starts behaving strangely. Like, if I throw my kunai it'll go through both of them and then I'm stuck unarmed against two dudes.
e: I thought the japanese(?) characters would make the game difficult to read, but that really isn't the case.
