[1] Downwell uses a palette of four colors, which default to black background and white outlines, with red as a highlight for gems, enemies and other important items, and blue for water environment features.

[5] In Downwell, players control a "curious man" named Welltaro,[6] who is at the local park one night when he decides to explore the depths of the well nearby.

Knowing that monsters are waiting for him inside, he straps on his gunboots and starts his trip downwards, killing his enemies to proceed and collect treasure.

[9] In other cases, the timevoids lead to a shop, where Welltaro is welcomed by a Jizō, who is taking the place of a shopkeeper, offering the player three different items in exchange for gems.

At that time, Fumoto had graduated in opera singing at the Tokyo University of the Arts, but felt like that was not the way he wanted to go in life.

[13] So, at the end of February 2014, Fumoto canceled his studies and went on to make multiple "game-a-week" projects, after he read about that idea in Rami Ismail's article on Gamasutra.

[14] Downwell was Fumoto's thirteenth project, in which he instantly saw a high potential and decided to continue its development.

[20] With constant support from Devolver Digital and Fumoto's continuous posting of GIF images led to the opening of the game's official website and the announcement for the late 2015 release on iOS and Microsoft Windows.

This does not only come from the not always perfect, fixed and predefined controls, but the whole game principle is obviously cut to the mobile market needs.
