This is hardly a game. You could get the same enjoyment out of playing Zelda with the controller upside-down and deciding that you lose if you touch a bush. It's the same thing. Actually, that would be better. You would actually have objectives to do in that game. You could try to beat a boss or even beat the game like that. This game has nothing like that. The only challenge in this game is its pointlessly convoluted controls. The reason that WASD "ruins" this game, as you say, is that there is literally nothing to it other than the arbitrary challenge that its bad controls present. You might as well make a game that can only be played with a laptop track pad. What's the point? Make good games, not hard games.
Also: Stop berating everybody who speaks the obvious and calls this a bad game. It makes you look bad. You made a game for us to play, not for yourself to gush over. Just because it's hard or because Markiplier played it doesn't mean that it's good. Anybody with common sense would stop playing this game after the first few levels. If you can't accept that, you can't design games. Period. You've delivered us the bare minimum and you're acting like it's a masterpiece.
Not only that, but I ain't even mad.
