cant get GetAsyncKeyState to work properly

[luckylarv]

Help deadline is tomorrow!! this is the only thing stopping my project from working. It compiles fine but just doesn't work as it should. I'm creating a basic RPG game and want the player to move a round a game map on the console. when I first press the down key, the character moves down once as he should. but then I can no longer move down any more. I then press the right key and a second image of the character appears to the right of the original position and I can no longer move right any more. please could you have a look at my code and see where I have gone wrong. I've spent the past 2 days trying different combinations and I just cant get it too work. hopefully a fresh set of eyes can see what's wrong

the * is the character. x's are walls
