Finished, there was a little surprise on how to get those last few notes!
Excellent game, supported you with a few bucks!
aahaha I must admit that,, *no*, I cheated (I found the point where you have to be pixelperfect, while confined on the top right part of the screen, too much for me!).
But I am sure I will havce occasions to replay it without savestates, since the game is pretty enjoyable even when you have explored the whole map!
