Kersploosh!

Kersploosh! is an action puzzle video game game based on the premise of what an object might see when it is thrown down a well. The goal of the game is to steer the player's chosen object to the bottom of the well as fast as possible without it breaking. The player can select various objects to throw down the well, including a stone, iron ball, bouncy ball, jewel, watermelon, and a matryoshka doll.

There are ten objects in total, with some being unlockable. Each object has unique stats for speed, boost speed, and health points. The bouncy ball, unlocked from the start, has a slow falling speed with infinite durability, whereas the water droplet, the final object unlocked, has the fastest fall speed that breaks in one hit. Before each level begins, a cutscene plays featuring humans throwing the selected object down the well, giving exposition on why the object is being discarded.

Kersploosh! was the first game on Nintendo 3DS developed by Poisoft, as well as the first game they created in collaboration with Nintendo. It was also the first game Poisoft released outside of Japan. Producer Hiroshi Ishikawa and director Akihiro Nakagawa, Poisoft's CEO, served as the two programmers, with Masahiro Kitago as a designer.

After receiving information about the 3DS, Poisoft set out to create a game that highlighted the system's stereoscopic 3D effect. Nakagawa originally proposed a design concept in the form of a fancy poem, asking the question of what is inside of a well. With this concept established, they created a racing game with the core theme of objects falling down a well, adding obstacles that accelerate and decelerate the player. The development team struggled implementing physics simulations when breaking objects while optimizing the game for the 3DS.

Kersploosh! received mixed or average reviews according to the review aggregators Metacritic and GameRankings. In their summary, Multiplayer.it described it as the "quintessential eShop game" on 3DS for its fast pace and cheap price.

The core gameplay was considered to be enjoyable by multiple gaming journalists. Mike Mason of Nintendo Life praised it for its addictiveness, as the stages provided tense moments that were never frustratingly difficult, but were short enough to replayed endlessly. Chris Carter of Destructoid claimed Kersploosh! was "a very brief, fleeting, yet enjoyable experience" that was fun to replay.
