> If you swim on the very top layer of water for too long (a couple of seconds) you can't simply look up and swim up, you get stuck under the water and have to use the space bar. It's not unbearable, but it is inconvenient and a little panic-inducing if you're not paying attention to your breathing and try to turn up.
