Wow, this is one of the strangest games I've played in awhile. All in all, I can't say I didn't like it, because it was quite innovative. You didn't give much description of how to get the medals. It is kind of fun to figure it out on your own. Since none of them are secret, I can give you a hint on at least one. You can get one of them by just leaving the island.
There was some uncertainty on how you exactly got done talking. The noise got a bit annoying. I guess I can't really blame you for that, since you can just mute the game. Of course, technically every game is one you can mute on your own computer. It's worth a shot.
