character dosent move in the correct direction when pushing the keys, i get stuck against walls and thus makes it inpossibe to play the game, can anyone help me pls?

I have an idea. If it isn't working, but other games do, check its directory. There might be a file that shouldn't be there thats restricting movement. But I don't have the comp version, so I wouldn't know. Or you could try to reinstall it.
