Heya! Thanks for checking the game out, and leaving your feedback :)
Yeah, this is an early prototype, so I haven't worked on sounds or character animations yet. New character sprites and 8-frame animations coming soon :)
Haha, great job with treasure hunting! That is about the number of endings there currently is. I am currently working on a feature that will let the player branch the story at any point in time, so there are more things to come :)
