I was really frustrated for the first couple minutes I was playing because it didn't seem like there was much I could to get between large gaps. If I hold B and P, I can't always make it to the next pipe before running out of water and I feel like I just take damage for no reason. And stopping seems really confusing - sometimes I release P and I stop immediately, sometimes I seem to drift for a while and it makes it hard to stay over a pipe for a refill.
Once I figured out I could just tap B to hover, basically indefinitely, it instead became frustrating because it seemed like I could keep going, but then birds would come out with no telegraphing to damage me. It just felt random at that point.
I recall one of you said it was meant to be like a QWOP style game, with hard controls. With QWOP, it explains that each key is a leg muscle, and so you can directly see what pressing the keys do to the player avatar. And your goal is to move forward, by using the keys to indirectly control the avatar. But here, the controls are just left, right, and rise, which is pretty direct control. So it seems like not a great comparison, besides the actual keys that are used. Also, I'm not sure why you would want to steer left in most cases.
