Beautiful minimalist art style!
The camera perspective makes it really hard to anticipate where to go, which makes me play more reactively.
I found it easier if I kept the boat closer to the top-left of the screen, so it'd be further away, as it increased my reaction window.
The gameplay is a bit too simple though so I didn't end up playing for long.
Having no sound at all is consistent with the minimalist approach I suppose, but I'd prefer it had at least ambient music.
