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!
