Under the username "jefequeso", David began to release games on Itch.io, Game Jolt, and Steam in 2014, including the freeware horror game Fingerbones and his first commercial horror game The Moon Sliver.

On December 10, 2018, David released Dusk, a retro-style first-person shooter game. For Dusk, Szymanski has been credited by SUPERJUMP with "single-handedly revitalizing the boomer-shooter genre". He then released Iron Lung on March 10, 2022, a submarine simulation horror game in which players navigate an ocean of blood on a moon. Sales increased after the Titan submersible implosion, which disconcerted Szymanski. He faced criticism online for increasing the price of the game by two dollars, to which he told those complaining to "go pirate it or something".
