Splishy Fish

The little fish swims forward on its own and sinks steadily unless you press. The task is to lift it just enough to slip through the gap between obstacles, one opening at a time. The mechanism is familiar, though the numbers behind it differ from its shelf-mates.

The gaps here are visibly wider than in the other timing games nearby, and the fish sinks more slowly too. The effect is that a single mistimed press leaves you room to recover. Anyone who tried this style once and abandoned it as too punishing has a sensible way back in.

One more thing worth knowing is that nothing is recorded between rounds. Whatever number you reach vanishes the moment the page closes, so keeping a record means writing it down or taking a screenshot yourself. It sounds like a shortcoming and it makes restarting easier, because there is nothing to protect.
