Haha, I totally agree with you on the grinning part. Everytime I hear the line "Guybrush Threepwood, Mighty Pirate™" I instantly grin.
The game works well indeed! I showed it to two friends of mine who hadn't seen the adventure game format yet and they were absolutely thrilled. So my expectancies have become pretty high! I hope many people will decide to try the game at some point and that the Adventure genre will make a comeback.
[edit] Just finished chapter 1. That was awesome.

I like how you can adjust the Hint Frequency too! I prefer playing with it set to 0 but when I'm really stuck I just increase it a bit and wait till I figure it out. Very handy little feature.
