Nice presentation. Beautiful island and parrot. Hand drawn maps would have been nicer, but probably wouldn't have fit the jam time I guess. But I'd even prefer a badly scribbled map (that would be funny) to a photocopy.
A parrot squeak on every dialog text would be cute.
I couldn't get past first clue (!You fooooound a clue, well doooone."). Tried many buttons and mouse clicks, not sure if the game hung up. EDIT: OK I started the game again. Looks like I forgot it was "X".
It also took me a bit to find out how to use dig. You have to look with "H" instead of the yellow dig symbol.
I love the setting and treasure hunting. Goes from way too easy to very difficult too quick for my taste.
EDIT2: Tried 2 times didn't find the treasure yet. I'm such a crappy pirate DX. But I did get better. Maybe 3rd time I'll get lucky.
