This was charming. Maybe the arrow buttons make it too obvious on where to go, and they could instead show up after being moused over? I didn't really feel like I was exploring like I have in older games I've played in this genre, rather just clicking on where to go next. Also maybe adding a few more screens in general, maybe intermediate steps like first zooming into the area of the lighthouse where the brick is before being able to interact with it?
Some other small criticisms: I would swap out of the font for something less.. MS powerpoint. The inventory could probably be collapsible or only appear when you obtain an item. I also noticed the music just kind of abruptly ends and doesn't loop again for a while, and the volume on it is a little too high.
Overall a good submission though!
