QWOP developer Bennet Foddy should suit your needs quite well. It's called Poleriders, and it's a competitive, two-player pole vaulting game. Only, instead of trying to use a pole to clear a raised bar, you're trying to either kick a ball through your opponent's goal, or kick your opponent's head, which is also tantalizingly ball-shaped.
Truth be told, we didn't find it nearly as difficult as QWOP -- though, we suppose difficulty will change based on the relative pole vaulting skill of your adversary. Vaulting against your roommate? No problem. Vaulting against four-time US Nation Outdoor Champion vaulter Jeff Hartwig? Well then, buster, you're in for a world of hurt.
