Venture into the Cavern of Longing for a short yet challenging journey in Deepest Sword. Developed by Cosmic Adventure Squad, this 2021 indie game tests your resolve as you plunge your sword into the dragon's heart.
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?
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.
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?)

Living Legend Achievement Updates
{STEAM_CLAN_IMAGE}/40608494/d10a4fa69b22098aafa6784303d05fea169d11bc.png We've just completed a minor update to the game! We heard your feedback and have made the "Living Legend" achievement easier to unlock. It now requires a completion time of under 3 minutes and 30 seconds to unlock, instead of 3 minutes. (This also means that the achievement has been reset for everyone.) We've also added a new "Best Time" display on the completion screen to help you improve your time. You can toggle it off in the Speedrun settings page if you don't like it. Additionally, if you're interested in supporting our development efforts, we've added a button that links to our Ko-fi on the credits page in the game's menu. Buy us a coffee :D (if you feel like it...) Thank you for playing Deepest Sword!Read full article on Community Announcements (stregawolf)
