I don't know if you'll see this, but the purple save crystal in the forest cave entrance causes the game to crash, with this error.
The file it says is "audio/se/%7B%22Name%22%3A%22Chime2%22%2C%22Volume%22%3A%2290%22%2C%22Pitch%22%3A%22100%22%2C%22Pan%22%3A%220%22%7D.ogg".
If I click "retry", the audio file plays as normal, but then the error screen immediately appears again.
It is only this crystal that causes this bug(that I know of).
Other than that, great game! I love it so far and I'm excited to see it continue being developed :3
