OoT Ocarina is a functional ocarina inspired by the Ocarina of Time game. It allows users to play a couple of songs using the ASDW keys, with the Shift key acting as the A button control. To reset, users can simply press the R key. The program is available as a free add-on for the Chrome browser.

While OoT Ocarina provides a unique experience for fans of the Ocarina of Time game, it is worth noting that the developer, Anders Sundheim, has lost interest in updating it. As a result, the program may not receive any future updates or improvements.

Overall, OoT Ocarina offers a nostalgic way to play songs from Ocarina of Time, but users should be aware that it may not be actively maintained by the developer.
