keeps getting stuck moving in one direction

This happens ALL THE TIME. I can easily fix it by pressing the button again, but it always fucks up at the most important moments and manages to kill me anyway. Also I keep rolling for no reason, which also keeps killing me. The problem only happens very quickly, but it's enough to make me completely hate this game, which is a shame because otherwise I really like it. In fact I just played it for like four hours straight, despite the fact that it's a complete piece of shit. Fix it now, or I'll leave this game forever. If you fix it I'll give you money. Fucking listen to me!!!! No excuses or I'm leaving and you won't have my money!!!!
