I love it! It's so cute.
But btw here are some suggestions to add {if you can, ofc}
1. An inventory of which and how many fish the ghost got.
2. Different things to do when clicking on items.
For example, when clicking the lamp, there will be a light turned on.
When clicking the couch, the ghost will sit on it.
When fishing, there are some trees in the background, when clicking, some leaves fall from it, or an apple!
