Evaluation

Deepest Sword launched on June 9, 2021 as a short physics platformer originally built for a game jam in 72 hours. The store description is transparent about this origin, describing it as a "short-yet-challenging" experience with a small set of features added for the Steam release (speedrun controls, key rebinding, achievements). The only post-launch patch arrived on June 14, 2021, tweaking an achievement unlock threshold and adding a best-time display — minor quality-of-life work consistent with a small, complete release. There have been no further patches, content updates, or development announcements for the game itself since then. The most recent developer post, dated June 23, 2026, is a plushie crowdfunding campaign update celebrating reaching their pledge goal. While it mentions the studio's continued work making "new games and experiences," it does not reference any planned updates or additions to Deepest Sword specifically. The game is treated as a finished product whose characters are now being made into merchandise. This is a complete, self-contained release with no announced future content.
Evidence
Minor patch released shortly after launch adjusting an achievement threshold and adding a best-time display. This is the only game update ever released and the last game-related communication until 2026.

About this game

Venture deep into the Cavern of Longing with your trusty yet unwieldy sword. Will your sword be long enough to pierce the dragon's heart? Or will your puny sword be nothing but a laughable object of ridicule in the dragon's eyes?

FEATURES:

  • You can't jump but you do have a sword, and you're not afraid to use it!
  • Marvel at your sword's length. Though if it's too long, it might get in the way...
  • Fulfill your deepest desires (like stabbing a dragon with your sword?)

Originally created in 72 hours for the Ludum Dare 48 Jam with the theme, "deeper and deeper". This version includes additional speedrun controls, key rebinding, and Steam achievement integration.
