Very nicely done! I enjoyed my time and pushed through to the end.
I did have one bug that almost prevented progress. When I click on the gold star in the inventory, the mouse cursor disappears. Makes it a guessing game where my cursor is as I try to click on something else, anything else, to get the cursor to reappear. I found that exiting full screen and re-entering full screen brings the cursor back (or getting lucky with my cursor and clicking on another inventory item also brings the cursor back).
