I really like the colorful and humorous aesthetic. The premise of lively but unsuspecting vacationers on the beach being encroached by a large tsunami that swiftly hides itself when needed all because a small pink bad-omen boat across the sea is trying to reach to a lighthouse is well executed with the sudden shifts in soundtracks, saturation and value. The solid paint art style also lends itself well to both phases of the game that it's a bit of a shame that there's not enough room for attention on it when playing.
The real criticisms, however, aren't due tot he aesthetic, though, yet they unfortunately dampen the humorous tone of the game significantly. The floating objects in the sea are cute details when engulfed by the tsunami, but the sailing ship does confuse players by being closer and holding a stronger silhouette compared to the pink ship off to the horizon. Perhaps changing it into something else would prevent such confusion. As for the gameplay itself, it is quite unforgiving on either its time constraints or length of the lifeguard watching the sea. Both factors often robbed me from my rounds, and many did not feel like my fault. One or the other could be adjusted to be slightly forgiving, though the increased frequency of the lifeguard checking the sea in the end should be kept for amping up the tension and eventual catharsis.
