I try not to worry about water.
In fact, thinking back across even my formative years as a Nintendo gamer, I remember actively seeking out water levels more than I do avoiding them. I have clear memories of honestly enjoying the swimming sections in Super Mario Bros., to the point where I’d avoid taking the Warp Zone in World 1-2 to skip to World 4 — because that would mean not getting to splash around in World 2-2. Bubble Man’s stage was always a joy to jump into in Mega Man 2, because I loved the extra-high heights that you could leap to reach once you went under the water (even if the ceiling was lined with spikes). In Star Fox 64, I’d always try to choose the route that let me play the Aquas level, since it was the one and only place in that game where Fox would pilot the Blue-Marine submarine. Water worlds were always weird and different, and I liked experiencing each one!
